Debian :: Total System Freeze / What Is Causing It?
Jun 16, 2011
I'm experiencing constant system freezes, and was wondering which log file to view in order to determine what is causing it. I switched over from linux mint as it was giving me the same issues now being experience on my debian setup.
When my system does freeze, the keyboard is unresponsive (caps lock won't even turn on) and I have to use the power button to get out of it. The only thing that does work is my wireless mouse which I can still move around.

I'm having some trouble hooking my external flatscreen monitor up to my Toshiba Tecra's docking station and having Mint (or Debian) be happy with it. The laptop uses a widescreen monitor but my external is a 4x3; I wonder if this is causing problems. Of course, it may just be the Intel 82801G graphics adapter.et things up properly in the Display Preferences config window (I'm using Gnome, btw) but when I hit apply, the system locks and I have to hard boot. I've never set up a linux box with multiple monitors before, let alone multiple monitors that require different resolutions.

I'm having a problem with my Ubuntu 10.10 system. After installing the OS it worked fine. But after one or two restarts it totally freezes i mean NO Ctrl+Alt+Bckspc , NO Ctrl+Alt+F1 and Ctrl+Alt+Del works for me. I have the same problem with Ubuntu 10.04 , 9.10 also. ( Only Ubuntu version 9.04 Works fine for me ). But i want to make use the latest one. code...
After Ubuntu fails some time it crush the GRUB loader, so that i can't boot windows either. Any buddy tell me why this happen to me?
I've try to install Linux Mint 10 also but it freezes while installing..!!
Now I loaded the openSUSE 11.4 milestone 3. It works fine for now but i can't connect to internet , it asks for "linux-atm-lib" . i don't know how to do that .

Ubuntu boots fine with wireless turned off via the laptop wireless button on the case, and fine with wireless on but no networks remembered, but as soon as I try to connect to a network, I get the strobing wireless icon in the top panel and then the whole system freezes. It switches to a black screen with a non-flashing terminal cursor in the top left corner of the screen plus a frozen mouse pointer in the last position from when Ubuntu was working. If I force a power-off after this, which I have to, then unless I manually turn off wifi using the laptop button then Ubuntu never boots and I just get a black screen after the BIOS screen. I can connect to the internet via wired connection.

Whilst watching my system boot I see the following error:
'drm: radeon pci probe error kernel requires firmware non-free'.
When I install the ATI graphics driver, sure - I get all the screen resolutions I could possibly want, but the cost appears to be that it makes it causes my system to freeze at the user name and password screen. Sometimes the cursor blinks teasingly, but nothing appears as I type; sometimes the cursor itself is frozen.
My question isn't about the myriad of theoretical key combinations that might work - none of them have thus far.
I'm wondering whether I can simply continue using the default driver that the debian installer (ver. 8 stable 'Jessie') installed on my system. It's true that I only get 3 choices of screen resolution - 1152x864, 1024x768, and 800x600 - but my system seems so much more stable than when I install the proprietary ATI driver.
Aside from the login screen freezing - more often than not, strange things were happening keyboard wise - especially when composing posts for forums - the cursor would suddenly jump to another line of previously composed text for example!
So, can I keep the default driver or is it best to install the ATI driver and attempt to troubleshoot it? Is it even possible to troubleshoot a problematic driver - I knew how to do such things in Windows, but still learning about linux.
Also, when my system freezes at login (for whatever reason), if I'm obliged to simply hit the laptop power button to power down and press it again to restart - is this potentially damaging/corrupting my system - Debian, or indeed my hard drive?
Going forward, is the ATI driver issue likely be addressed in future Debian releases? Obviously, I would prefer to have the proper driver installed so as to have more screen resolution options - since I will be using my laptop for developing and testing web sites.

I have a very simple bash script that just runs a series of backups using tar; for example, one of the lines reads:tar -czvpf /srv/backups/backup_home.tar.gz /homeThis script is scheduled to run every Friday, but occasionally I will schedule it to run before using 'at'. The script is located on the same disk as the backups are saved, I then transfer them off the machine manually (I've yet to automate this). I am only compressing files that are located on the server's disk, no files are being transferred over the network at all.
The problem is, occasionally it appears to be causing the 'server' I have running all the time to completely freeze. When this happens the machine does not power down and there are no entries in the log that indicate a problem. Everything simply stops until I press the reset button. Note that this issue also happens when you run the script manually and not just when it is run via cron or at.I *think* this might be happening when a large file is being compressed, but I'm not certain.

I installed 10.10 this morning from the live CD. Everything working perfectly whilst at home, but now I'm on the move I'm having troubles.At my parents' house trying to connect to their wifi. Wifi is on, their network is detected, I can go in and enter the WAP key and I get the strobing wifi icon in the top panel as though it's signing in, but after about 4 seconds I get a black screen and everything freezes. All that remains on the screen is the mouse pointer in its last position and a non-flashing cursor in the top left.

I have installed Slackware 13.1 without a problem and have a working wired ethernet connection. However I need to set up wireless but each time I try to do this using wicd I have a total system crash during the start up screens at the very last line before the welcome line appears.
Nothing works to resolve it, and I need to press and hold the start button and restart. I have checked the md5sum, installed the software again several times but the same happens each time which results in me having to reinstall.
I have installed wicd using slackpkg update, then slackpkg install wicd.
I have also tried downloading wicd from the slackware /extras folder and installing it on its own. Either way the same happens.
I have tried various manual approaches to setting up wireless following various links but again without success.
I now have a clean install again but am not wanting the same to happen.
Can anyone suggest what I might need to do?
I am using an intel Pentium 4, 2.53 ghz, 512Mb ram, GeForce4 MX 440.

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've been having trouble lately with firefox freezing. For awhile I couldn't figure out what was causing it as it seemed random. But I think I narrowed down the problem to the mplayer plugin. Whenever I go to a site that has streaming video, the mplayer plugin would start reading the stream, but then display "stopped". Now sometimes when it does this firefox would freeze, but sometimes it wouldn't freeze till I start mousing over my bookmark tabs, then it would freeze my entire desktop. I can move my mouse but not much else. I can do a ctrl-alt-backspace to reload the xserver. Has anyone else noticed this? Also, can some help me troubleshoot this. I've removed and then re-installed firefox and the myplayer plugin; deleted my .mozilla directory; changed profiles. Is there anything else I can do?
Here are the package details:
Code:
Repository: @System
Name: MozillaFirefox
Version: 3.6.15-0.2.2
Arch: x86_64

i've been able to narrow down a freezing issue on my laptop, down to NetworkManager when i have a cifs share mounted in fstab.removing the cifs mount, or using 'ifup' method appears to fix the issue.the problem is when my laptop resumes from sleep, and when using NetworkManager with cifs share, then i get a 20second freeze when using the launcher while the network sorts itself out. this happens on either wifi or wired connections. this freeze only occurs when using the Launcher for the first time after resume. if i dont use the launcher then everything is fine untill i do (ie: i have network access and desktop shortcuts work fine)

We have an old Zonet 10/100 switch in our home network that locks up whenever there's a power glitch longer than about a microsecond. (OK. It's not that bad but if the lights flicker, I usually end up going down to the basement to see if the switch is hung.) None of the computers or peripherals are affected by the glitches, BTW. Power-cycle the switch and everything starts working again. After putting up with this for months I finally picked up a Netgear 8-port 10/100/1000 switch to replace the Zonet. Unfortunately, when the Netgear switch is in the network, everything slows to a crawl before completely freezing up. Pinging other systems barely worksname would not work.Pinging another system by its IP address worked a little but packet losses of 70%-80% were the best I saw. At first. Then it gets to where the loss is 100%.
All systems were rebooted after the Netgear switch was inserted into the network. The systems that were capable of gigabit connections autosensed the new switch and set their port speed accordingly. And that's about all that works when the Netgear switch is present. (The Zonet is back in the network now.)One thing I have not tried is forcing the port speed on the gigabit-capable systems to 100Mb and re-inserting the Netgear switch into the network to see if the problem if due to running some of the ports at 1000Mb.The systems on the network are running various versions of Linux (with different kernel versions, of course). Most are due for upgrades to get them current but I was planning on hitting the systems that had gigabit-capable ethernet interfaces thinking that a.) 100Mb speeds have been around forever and no problems have been seen when everything was running at 100Mb in the past and b.) the gigabit support for the older kernels should be better (one system only supports an MTA of 1500 max at 1000Mb).

So I have recently been making attempts at setting up my RTL8192SU chipset usb wifi. After struggling to set it up by following the steps on this link: [URL]../url?sa=t&jUyXQukrfIw After doing this I had no idea what it was supposed to look like but It did display several warnings along the lines of "warning: cast from pointer to integer of different size" I continued following steps as another error occurred "cp cannot stat autoconf.rtl8712_usb_linux.h" I then entered sudo modprobe 8712u and my screen went black i was forced shut down . Upon rebooting I found it also would lock up if my usb device was plugged in It will boot with it unplugged but as soon as it is plugged in again it will lock up my system and send it to a black screen.

I'm having a few problems with XOrg freezing while playing World of Goo (not the worlds most intense game for graphics, but seemingly too much for my rig). I initially posted on the developer's forums, but they said a full X freeze wouldn't be the game. Testing with BZFlag got me a full Xorg freeze even quicker than with WoG. Later I even tried glxgears to see how well it ran and even that froze the system! My only way of recovering is SysReq-REISUB.
Specs/system details:
2.4GHz Core 2 Duo (E6600)
2GB RAM
Radeon X1950XTX using the open source drivers
openSUSE 11.2 (64-bit - patched up to date and without an xorg.conf)
[code].....
So, is there a fix for the huge instability with 3D graphics, or am I stuck between a rock and a hard place with the options of outdated official drivers that may not work with the latest kernels (and would need manually rebuilding even if they did) or flakey open drivers that are guaranteed to freeze at some point, it is just a matter of when?

I'm experiencing some weird short freezing issues in Squeeze and / or unstable. Everything works as usual, then the system will freeze for some seconds if I don't do anything, or resume faster if I move the mouse or hit a key on the keyboard. I thought it was a wifi related problem, as I have an intel iwl4965 , here is what I often see in dmesg:
[ 2608.910307] iwl4965 0000:06:00.0: Queue 4 stuck for 2000 ms.
[ 2608.910317] iwl4965 0000:06:00.0: On demand firmware reload
[ 2608.912832] ieee80211 phy0: Hardware restart was requested

i'm running debian on a custom-built (no brand) box, which has been up and running for, maybe, 3-4 years with no issues whatsoever. all good parts... asus mbo, athlon, wd hd, etc. lately, every once in a while - like, say, every couple of days - i hear a "beep" from the box and the system freezes... lose the keyboard and mouse, and the display stays up but also freezes (for example, if a videos vid was playing, it would just freeze). have to physically reboot to get the system back. i assume this has nothing to do with the os or any app (although i'm usually browsing with chrome or ff when it happens). not being a hardware guy... can anybody clue me in as to how to figure out what's causing the problem?

I'm very new to Linux and have installed debian Lenny.
but I have met some problems. The biggerst one is that I cant start debian.
To be more exactly, debian freeze after i come to the loggin scean, I cant move the mouse and i cant wright.
You may say that this is hardwear error but its not, cus i can run grubs singel-user-mode and do whatever i want in the shell.
so my question is, how do i fix this from shell. I think maby I shld change something in xorg.conf but not sure what, and how.

When I try to shut my PC down (press the shutdown button in KDE 4.3.4), the desktop quits, but the console screen does not appear (the CTRL+ALT+F1 screen). Well, technically speaking it appears but only a still (not blinking) cursor is shown, otherwise the whole screen is blank. This means that not only the X freezes but whole system, because the keyboard is unresponsive too. It happend multiple times now, and every time I reboot after such event, some kde rc files (amarokrc, kmailrc, etc...) get deleted due to the automated filesystem check (unclean umount), which means that I have to reconfigure these apps again.
My home partition is on a separate EXT2 partition (this way I have full r/w access from winxp) and every time this is the only one which gets corrupted. The system partition (which is EXT3) is always intact (no fsck starts on boot). I'm using Debian Squeeze by the way.

I made a fresh installation of Debian.
Code: Select all[VOSTRO200@root]#uname --all
Linux VOSTRO200 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u1 x86_64 GNU/Linux
I changed to the kde desktop environment. I logged in as a normal user, and left the computer running for a few hours. when I came back the screen was turned off and the system does not respond to mouse movement, pressing the keyboard, or any combination thereof. I tried
Code: Select allCtr+Alt+F1,
CapsLock
First time i touched keyboard the led of numlock turned off, and never back. Blanking the screen itself does not cause a system crash, this occurs after several hours of inactivity.

I was just trying to get used to everything and I noticed something in the task bar that said you have updates that failed to install (or something along those lines). So I opted to install them manually with YAST2 and during the installation some of the files were failing to download, I was unsure what to do with these files (their was a ton of them, I had to actually sit at my pc for over an hour because I couldn't let it go through on it's own due to all the failing downloads and installs) and so I just decided to skip them, everything seemed to be going along normally. Then my computer froze, so I restarted and tried to boot into opensuse and it kept freezing, (I even went to my brothers house to play the xbox with him for a while) and no matter how long I waited for it wouldn't boot into opensuse. I tried the failsafe mode and it just kept coming up with an error (I probably should have written the error down, I wasn't really thinking about that at the time) and after about half a dozen tries, decided to reformat everything all over again.
So with these failing downloads in YAST2, what am I supposed to do with them? If I retry they just keep failing, so the only other options are abort and skip, am I supposed to skip them or is that what caused this to happen in the first place?

I want to calculate the total amount of memory used by the system, Someone please confirm if the below formula is correct.Quote:
((memUsed-mebBuffers-memCached)*100)/memUsed => totalMemoryUsed%
Code:
free -o
total used free shared buffers cached
Mem: 8167004 8115292 51712 0 87680 1444676
Swap: 8388584 3252996 5135588
((8115292-87680-1444676)*100/8115292) => 81%
As per the above calculation 81% of memory is used.Is this correct? and if so Am I running out of memory?what is the limit in % that I should maintain for a better performance?

I'm running firefox 3.6.12 with the following add ons installed: Windows Media Player 10, Div X web player 1.4.0.233 and Flash 10.1 r102. Ubuntu is 32 bit as is the Flash plugin. Quicktime, VLC and iTunes application detector are installed but disabled. I get recurrent episodes whilst using firefox where the entire screen goes grey/black and after a minute or so the login screen appears and I have to enter my password get back to the desktop. I suspect that this is flash related as it normally occurs after watching a few minutes of video. Disabling flash reduces the frequency of the problem but does not eliminate it.

Today while browsing the web and attempting to listen to a mp3 file on the site of a musician, this laptop with Lucid CRASHED badly! It went into a black screen and the only solution was a reboot! I am not a masochist, but I could repeat the crash a couple of times just to verify it.
This is the worst crash that I have seen on GNU/Linux! I expect things to go down in a more controlled way: maybe first the crash of a plug-in, then the crash of a web browser, eventually the crash of a windows manager. But I don't like seeing that playing an mp3 is leading to kernel crash on what is supposed to be a LTS-release!
Any observations of similar behavior or hints on the cause? Is it possible that the crash is related to intel graphics 85x on this system that are now very problematic on Lucid?
By the way, the music file in question is probably not malformed and plays perfectly on Mac and Windows. I am digging into system logs to try to find any record of the problem. For the the record: I've been around Ubuntu since 5.04, on Linux since 2003, on Unix since 1988, and on computers since 1979.

How can you give total access to the system to a user other than root?
* Make the user a member of the root group.
* Change the UID of the user to 0.
* Add the user to the /etc/sudoers file.
I think none of these are correct answers.

So this just started a few days ago... maybe 7 at the most.
I am working along, and screen goes black, or just freezes... the lights on my laptop start blinking and becomes everything becomes unresponsive.
I have noticed it is usually when I am Using Firefox and Flash content. I have also noticed it happens when using Deluge, but it usually takes 5 minutes to kick in.
I am using firefox at the moment, but I am sure if I load up a ..... video, it will lock up on me again.

I have an intermittent and very irritating problem. I have a desktop PC with Ubuntu Lucid installed that I use primarily for watching films using VLC. Every so often (seemingly at random) around half way through the film the whole thing locks up - the video freezes, the audio skips (like a stuck record) and the system is unresponsive - the only cure is a full restart with the power button. Im at a loss as to how to try and diagnose this issue. Is there a log somewhere that might have the info after I reboot?
Usefull info on the system:
- AMD processor - 64 capable but running 32 as I wanted to avoid issues.
- grpahics is via an NVIDIA Geforce FX5500 (PCI interface NOT AGP)
- Restricted NVIDIA drivers installed and working
- Also useful to note that this problem occured when using an AGP ATI Radeon 9200 (using the standard open source drivers of course). In fact the problem was worse with the ATI - the frequency of lock ups is less with the new set up.
