OpenSUSE Hardware :: After Adding RAM Modules - Random Screen Freeze/lockup
Jan 11, 2011
Basically when I add more than a single 2gb RAM module, my computer starts randomly crashing every half hour or so, the screen freezes with no response. I have tested the RAM with memtest 86+, it only happens when there is more than one module. The system is openSuse 11.2 64bit and it had a single 2gb RAM module when I first installed it, and removing all but this seemingly fixes the issue. The following is the error message I get when the system crashes, It seems to continue messaging after the initial visual lockup.
I don't know what the problem is, but from searching the web it could be a number of problems, the memory is not being allocated correctly or it maybe there's some conflict no between my ATI HD card/driver (latest driver from ATI repo).
Running updated 11.04 on a older Dell Precision 360n. Been having random system freezes for the past month that requires a hard restart (REISUB doesn't work) each time. Sometimes the caps lock and scroll lock LEDs blink, other times not. sometimes it happens during boot, other times during normal usage. There hasn't been anything in any of the logs (except once, which I'll post below). This happened running 10.04 and 10.10 as well. I've run PC-check a few times and all hardware diagnostics have passed. Until today, i've been able to boot and run Trinity Rescue Kit 3.4 to mount the disk and examine the logs (and do backups), but now TRK won't boot and spews kernel panics when loading.
I've just installed OpenSuse 11.3 on my two Sony Vaio VPCF11Z1E machines (which have a Geforce GT 330M graphics card).Both machines appear to setup correctly and behave normally, but at seemingly random intervals (of the order of magnitude of 15-30 minutes) the whole system locks up for no readily apparent reason. I can still move the mouse pointer around the screen, but I cannot click on anything, and the whole keyboard is unresponsive (including any reasonable ctrl-alt-xxx which might normally help). The only way to get out of this seems to be to press and hold the power button to shut the whole machine off (which is not ideal!)
I'm experiencing random lockups. There are 2 types.1st time this happened when I enabled Kwin compositing effects. The screen turned black and it froze, the mouse pointer froze. Nothing would move. 5 Minutes later I just hard reset the Laptop. I was afraid something could be corrupted as it was shutdown in a bad way. On boot up Kwin's compositing effects were in place.Randomly working on the laptop, everything will freeze except the mouse pointer. This happens like once in a while though.I have a feeling this has something to do with my Dell Studio 1555 Intel GM4500 MHD graphics.
I downloaded and burnt the Kubuntu 10.04 release to a CD. I tried to install it. First time, couldn't find the disks and eventually it froze. Ok, second try, when it's contacting the "time server" (or whatever) another freeze, but this time I notice everything is running fine and then get a nice little image with the current time (increasing seconds and all). Third attemp, clicked the "update this installer" and it went fine. "Yay!" I thought. Well, a few minutes in my beautiful 10.04 system and again, another freeze. Hit the power button and to my surprise a "Shutdown" dialog shows up with a countdown. After 30 seconds it logs out and mouse is working again. I log back in and come here to write this long post, and as I was writing the title "Random mouse/ke..." guess what? Yeah, it froze again. And the little bar that goes after the writing continued happily blinking. Hit the power button but this time mouse and keyboard were still frozen in the login screen.
Short version: mouse and keyboard randomly freeze while the rest of the system apparently work fine.
I am having a problem with lockups on a new FC12 box (dual core 3 ghz, 4 gb memory,nvidia 8400gs). This happens reliably when replaying MythTV videos, but also randomly at other times using other apps (I suspect also boot but I can't be sure; it just occasionally stalls part way through the boot display).
Usually but not always this is accompanied by a kernel panic (caps lock + scroll lock lights flash on keyboard).
I did a core dump with kdump and it reports: Thread 1 (<main task>): Cannot access memory at address 0xffff880028025b70I am in the process of running memtest86+ right now. It's been through several passes without errors. I'm going to let it run some more, but if that is dependable it's looking like the RAM sticks are not the problem.
I've been running F@H on my system for a while now, these specs:
ASUS Rampage Formula Q9450 @ 3.6Ghz 4GB DDR2 8800GT 512MB Fedora 12
Running various different nvidia drivers, with working 3D, and running the latest nvidia drivers with cuda for GPU2 folding + SMP folding.
I decided to add a 9800GT to the machine for more folding PPD, and I've run into some issues.
Firstly there were problems starting X, it would hang as it started or even before it started, so I switched to RPMFusion's repo drivers which have the VGA_ARB patch applied. This now gets me into X and working 2D.
The problem I have is, although the system is completely stable running folding on all four cores, SMP, 24/7, as soon as I start anything involving 3D (such as glxgears) it will run for 3 seconds then hardlock the machine. I mean seriously lock it, no switching to terminals, and an ssh session into it from another PC dies.
Its the same with any other driver that will boot into X with the VGA_ARB patch (talking nvidia binary here).
Both cards work perfectly individually, AND both cards work, including full 3D in Windows 7 when together, which would tend to rule out a hardware fault.
I just installed Fedora 12. Now i've seen a few other threads but they seem to have all the conclusion that its the Nvidia drivers at fault. Well i have an ATI Mobility Radeon 3400 series. I can login, and navigate for a little bit, then it just randomly freezes. I've booted to both gnome and KDE, kde freezes almost immediately w/o letting me navigate much. Gnome takes a bit and then freezes on me. I managed to login once and go like 6 minutes then i thought it was worked out, rebooted and boom, froze up again. I can still move my mouse but can't click or use keyboard. Ctrl+Alt+Backspace doesn't work either .....
I have a couple of question regarding the screen blanker on Gnome desktop.I used to use a 1024x768 display with previous openSUSE distribution. With 11.3, I discovered the new "auto-configure" X feature. The default screen mode was 1600x1200, but I changed it to 1280x1024.My gfx board is a Matrox G400 DH. Hardware acceleration is disable because of a missing mga_dri.so (fall back to software rendering).I find some screen blanker modules are using almost all the CPU cycles. Animations are very slow, and it can take long before a keyboard hit or mouse movement makes to leave the blanker.
So the questions:- Is there a way to define another (smaller) screen resolution just for the blanker ?- Who should I try to convince to add mga_dri.so back in Mesa again ?- When the monitor go to sleep (DPMS), the blanker still is running, uselessly consuming CPU times. (I can see that because at the first mouse/kbd event, the monitor wake up and shows the blanker running.) Is there a way to configure the blanker to stop running when the monitor is sleeping ?- There are some modules which load images from HD (not the diaporama which load images in ~/images). But the shown image is always the default built-in one. Where is the blanker trying to load images from ?
This has been confusing me for a while. It usually takes about 4 or 5 times of hitting the power button for it to start up to the login screen. All it does is go to the Ubuntu splash screen and that's it. The colored dots don't change or anything. It just sits there. I ran the memory test to be sure it wasn't RAM and it ran fine.
I've been getting a random hard freeze, in both windows and linux, so I'm pretty sure it's not a software thing. I've run memory diagnostics in windows and it came out fine, I'm not sure what other diagnostics I can run. what tools can I run in linux that might help me further diagnose the problem? I haven't installed any new hardware, and I blasted the inside with some compressed air to err on the side of caution, but I still have problems. i'm running the latest ubuntu ver btw
I had installed Ubuntu Studio Natty from scratch onto a fresh partition, keeping Ubuntu Studio Maverick on another partition until I was sure Natty was working right. But whenever I tried using Natty the system would totally freeze, or so it seemed. Everything would freeze except the mouse pointer. Even the clock, which I have displaying seconds, would stop counting. I searched all over and there seemed to be little agreement about the cause of this, but a lot of people seemed to be experiencing it. It seemed to me however that there was a trend toward blaming new 3D features, and some tips suggested starting with 3D display features disabled; I forget now how to do that, but I do know that it didn't work for me.
After sort of giving up for a couple of months and going back to Maverick I had the idea to try installing (actually "activating") the Nvidia proprietary driver---and the problem seems to have been totally fixed. That's literally all I did, and for at least a few weeks, maybe a month or more, no freezes.
I should add that after a while the symptoms revealed that it wasn't necessarily that the computer was freezing, it was that it would rev up to maximum CPU usage and stay there, with a restart the only solution, until it would start again, seemingly at random, after several minutes to a half hour usually.
My problem is that my server randomly hangs. If I remember right it started after an kernel update (can't really remember if it was a kernel update specific, but I did install new updates before this problem occurred), and then I noticed my server was down one day, after that the problems/random freezes continued. And there are no pattern/interval between the freeze ups.
I think that all this started for about 3 weeks ago, so I've never had this problem with Ubuntu 10.04 before.
At first, I thought the source to my problem was an old IDE which I accidentally left in when installing Ubuntu at the first time, so GRUB was sitting on that one. So I backed up almost all of my data, reinstalled Ubuntu 10.04 (downloaded from the website) but this time without the old IDE drive. Everything seemed to work, had no crashes or freezes. I do have to mention that the same thing happend to the live CD before I removed the old IDE.
But now the fresh install of Ubuntu seems to hang too. And the worst part of this is that I can't really do anything about it to test or look up what may cause the problem, as I have to access it remotely because I'm on vacation right now (I'll have to get my friend over there and restart it).
When the computer hangs it comes inaccessible from the network, can't even see that it is up in my router. But I do know it is running, else it would have been shut off and then started up again and work.
Before I re-installed it, this problem could be reproduced by surfing the web and watching flash videos in either chromium or Firefox.
And I do know it sounds silly to run a server with the desktop edition installed, but if I don't have any other computer accessible, I use my server instead.
I'm running Fedora 12 with GNOME on an old Toshiba Satellite A15. From time to time I get a system freeze, where everything stops working besides the touch pad (I can move the cursor, just can't click on anything). When I boot up, I see an error message that it skips past before I can read anything, although I have spotted the snippets 'pci' 'error' and what appears to be the 0x at the start of a memory address. When I try and shut down the system (going either by command line or the System->Shut Down part), I get to the part where it says "Unmounting filesystems..." and then it stops right there. When I boot it back up, I get an error that says "A crash in package kernel has been detected."
The same happens when I boot up after the hard freeze. It seems more frequent when I have a heavy load on system memory, but for the most part it seems random. I've seen it crash after 5 minutes with only Pidgin or gedit open, I've seen it run for weeks with over 100 Firefox tabs, Pidgin, 3 documents, and GIMP running, but it seems more likely in the second scenario. It also seems to have a chance of freezing again within 5 minutes of rebooting (even if I don't touch anything after login). I ran Fedora 8 and Fedora 10 on this computer just fine, with most of the same system settings (copied my /home folder for each upgrade). I have a dual-boot system (XP/Fedora), with a third partition for data and a 200MB partition for the boot loader. The partition with Fedora is encrypted, and the crashing while trying to unmount the filesystem implies to me that might be the problem, but whatever it is, it wasn't in Fedora 8 or 10 (at least as far as I could tell).
As this thread [URL]... reached over thousand posts, it's obvious that these freezes (which actually boils down to keyboard and mouse not being listened to by X server, so "not working") hit large numbers of Ubuntu users. As that thread is already very large and hard to read I'd like to advance a hypothesis here : This problem occurs only on multi-core CPUs.
I've installed 10.04 on two machines: and old box with a Duron and new one with quad core. The old box runs just fine with 10.04. The new one - you know Has anyone exeprienced this problem on a single core machine?
I am a Ubuntu user since a few years (Breezy Badger was my first) now but I still don't know much about computers or commands so please bear with me. I used 10.04 on my HP pavillion PC of two years old without any problems. Now I upgraded to 10.10 with update manager. And it boots fine, but whatever I do, after aprox. 10 minutes everything just freezes. And I don't remember the magic phrase for soft reset, so I hit the power button.
I have searched the forums and could not find a satisfactory answer to my problem. I found this thread [URL] but have no idea how to do what's requested. Could anyone please tell me what to do?I know how to open a terminal, and type a command or two but that's basically it.
I seem to be having a problem on the new Kernel (2.6.35-23) with the system randomly freezing.
I have installed a number of things in recent days leading up to this problem, but when i boot with the old kernel i don't seem to have any issues. From this i am guessing its the new kernel.
The freezing seems (although i am not sure) to be worse when Rhythmbox is running. When it happens everything freezes, the playing song skips, replaying the same one second of music over and over. All the hotkeys stop and the mouse cursor stops responding.
I have seen people talking about system logs to look at system crashes but i don't know how to show those. I also doubt my ability to interpret them.
i've had a problema with opensuse 11.3. Sometimes (3 times) the O.S. is freeze. STOP everything. And i had that shutdown with button. I think that the problem is with KDE, but i dont know.
I was opening up a ODG doc and then my pc froze up. I powered it down, but now its telling me upon trying to open up the document again that someone else is accessing it so its locked.
It seems that my Ubuntu 10.04 (clean install) to randomly freeze / hang (mouse/keyboard unresponsive, only a hard reboot is available as option) but with no garbled screens/windows/etc. There's no pattern why or any application that could be responsible. It could happen ten minutes after it is started or after 2 days but at some point and suddenly the system will become totally unresponsive, freeze and hang up. I used the same PC with Karmic Koala and releases before that (sometimes on for days) with no such problem so it shouldn't be a hardware problem.
I thoroughly check system logs after the hard reboot (System > Administation > Log File Viewer) and there's no entry around the time of each freeze / hang to pinpoint me to something.
The only thing that is certain is that the following errors / warnings always appear in .xsession-errors file:
Here is also some info about my system: M/B: ASUS P4R800-V DELUXE CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz RAM: 1GB Graphics: ATI Radeon 9100 IGP
I am running Ubuntu 10.04, randomly while working in gnome with no particular application I get a freeze periodically. Neither the mouse or the keyboard will respond. I am running it on a lenovo Z61m laptop. I have had previous experience with Posix systems but I am a recent migrant from XP as my primary operating system. I never had such an issue with this computer which leads me to believe that it is not a hardware issue.
Everytime I use keyboard shortcut such as Alt-Tab to switch windows, my whole ubuntu freezes. I can still move mouse pointer but I cannot click anything. Anyone has an idea?

At random intervals the video output is turned off for 2 - 3 seconds giving a black screen. (I suspect the 2 - 3 second blank time is how long it takes the monitor to recover after a loss of input signal.) The interval between events can vary from 1 minute to an hour to more than a week, and recently more than a month. Sometimes I get several per hour; other times not for two weeks. Hmm, there was a kernel update in the last week or so.At one time the cause was pointed at a USB driver problem since a number of USB log entries occurred at the same time as the screen blanking. That is not the case here;here is nothing in </var/log/messages> (or the dmesg output) that is anywhere near when a screen event happens.
I'll start at the beginning. The problem i am about to describe occured in ubuntu 9.10 for the first time (https://bugs.launchpad.net/ubuntu/+bug/480850) and is ironically partly responsible for my switching to debian. which i don't regret, but it seems i can't run from the bug any longer because now it's in squeeze, so i want to fix it or make a proper bug report:
Steps to Reproduce: 1: Suspend Laptop to RAM 2: Resume from Suspend 3: Wait and see, preferably monitoring top: At some random time, ranging from immediately (black screen after resume) to several hours later, the system will become unresponsive. Switching to tty1 or Alt+Print+K does not work, Alt+Print+REISUB does work. Each freeze is anticipated by a random process (this time it was mandb, was installing something) hogging 100% of CPU, then the System becomes gradually unresponsive within a minute or so (panel, metacity, finally mouse cursor freezes too). Alternatively, in case of a black screen immediately upon resume, Alt+Print+K works (EDIT: or not), and the system remains usable. Additionally, i don't know if this is related, i noticed one process using 9999% of CPU for a second according to top, just thought i'd mention it. This bug constitutes a regression, suspend does work flawlessly on this Laptop in Lenny.
The above is how it presented itself at the beginning on a fresh squeeze install, however, after two days of trying, i additionally get kerneloops messages i did not get before (again, after at least one suspend to ram) and after that the system becomes generally unstable (random applications won't properly open or terminate, including nautilus, evolution, iceweasel). Can this be due to secondary damage from the freezes and alt+print+reisubbing repeatedly?
The good news is, apart from this probably already damaged squeeze install, i have another one on one of my playground partitons, where i avoided suspend so far, so i can still try things out there. (it's kde, but i don't think it's related to the desktop environment).
I am using Ubuntu Lucid Lynx 10.04 (64 bits) in my Asus U30JC laptop (Core i3 M350, intel 4500MHD + nvidia 310M with nvidia Optimus, 4GB RAM). I am content with Lucid and I don't want to upgrade to 10.10 for now. However I read that the new 2.6.36 kernel has some good improvements, such as improving system interactivity while intensive I/O (such as copying large files), and improved energy management for i3/i5 processors (which I hope translates into more battery time, which is a problem of Ubuntu vs Win7 in my laptop).
I discovered I had 2 options: compile the kernel myself, or use the Ubuntu Kernel PPA (maintained by the Ubuntu Kernel Team). I decided to use the PPA, so I added it to my software sources and installed the generic"linux-lts-backport-natty" kernel (2.6.36-1).
Package installation went fine, and after reboot, I could log in to the desktop no problem. Everything seemed fine, but after a few minutes, the system freezes completely: mouse did not move, none of the indicators moved, even Ctrl + Alt + F1 did not work.Where is the log file where there might be a message related to the freeze? Do you think that the kernel developers would try to fix a bug that probably only affects people running the 2.6.36-1 kernel on a distribution that was not built around it?
Ubuntu 9.04, all updates Latest firmware, etc abit SG-95 motherboard 2 GB Ultra DDR2 Intel Celeron 360 cpu PNY GeForce 9500 GT video
Started 2 weeks ago, random and total freeze of system (video, keyboard, mouse).
Nothing useful in th log, other than it occurs at the same time syslogd restart show up in the log.
I don't even know where to begin, or how to troubleshoot the issue if nothing shows up in the log... could use some help, please.
Problem occurs with or without the nvidia drivers installed. Ubuntu or windows, same thing..connected or not connected to the internet
I've ran every memory test I can find, with no issues reported. HD seems OK. No other symptom that I can find, other than it croaking, usually when I'm in the middle of a broadcast or recording.
Is the only machine I have for now, I need to figure out what's wrong and replace it as quickly as possible, so I can get back to work.
I am administrating a server with CentOS installed. It came with qmail and courier-imap preinstalled, and Plesk.I need to manually add email accounts outside of Plesk, because my 1-domain Plesk license only allows the creation of one email address (yes, it sucks).
When I say add email account I mean creating a new email address, have email for that address be stored in its maildir, and have a corresponding imap (and hipefully also pop3) account that will be able to read that mail. All this with virtual domains.I've already found out how to create the new email addresses for qmail, so that email for the new email address is being delivered correctly. Now I need to create the imap/pop3 accounts for courier.
For the qmail part, I create a folder in in /var/qmail/mailnames/virtualdomain.org/username and a maildir called Maildir inside it. This is how the first mail address was created by Plesk and i'd like to maintain the same structure. As I've said, the qmail part is already working, I need to get the courier-imap part to work. Ideally, it should accept login with both short (i.e. myuser) and long (i.e. myuser@virtualdomain.org) user names.
Currently the only authentication module that is enabled in courier-imap is authpsa, which is Plesk's authentication module.in order to add more authentication modules, do I just need to add them to the authentication module list in /etc/courierimap/imapd, or do I need to reinstall courier-imap with support for such authentication modules? I thought I would only need to add them to the list, but I've noticed that the /usr/lib/courier-imap/authlib/ folder only contains a binary called "authpsa". Does that mean that other authentication modules are not even installed? If so, can I install them without reinstalling courier?
The second question is, what would be the most recommended authentication module that would make it easiest to create new email addresses/accounts from the command line? I need to be able to write a shell scripts capable of creating a new email address with all that is needed, and I'd like to keep this script as simple as possible, so for example I'd avoid mysql-based authentication as it sounds rather complicated. And the last question is, if I do need to reinstall courier-imap, how can I install a package without recompiling it? Will my one existing mailbox keep working?
When it launches, sometimes a few mins later, the upper left of the screen (where gnome-terminal sits) freezes and becomes unresponsive. The cursor always stays as the 'text entry' cursor when in the region. If I alt-drag the window and close, nothing changes.It only goes away when I right click the area (even if I have moved/closed the terminal window) I have terminal options so I select 'close' then the screen resumes.
