View 4 Repliesi've got a non-typical problem here. i've got kvm-ed freebsd (its not so important here) stored on a block device - /dev/sdb8. i wanted to install fedora rawhide there but first i thought it's a good idea to do some backup. so here we go dd if=/dev/sdb8 of=freebsd.img bs=4k
theoretically, dd should do the thing without saying a word, but it doesn't. every time it stops after reaching 16GB filesize (partition is about 35GB) and completely locks the system (only reset helps).the dump worked only once, but when i tried to compress this big image 7z got stucked too and the system froze . the problem occurs when copying to the same drive or to different drive. i've got a partial kerneloops logs, but so far i haven't found the answer.

I just get upgraded from F10 to F12. I am having problem with switching between users. The system would freeze up and the mouse would move unresponsively, could not restart system with Ctrl-Alt Del. When it freeze up, it doesn't give error anyway on next start.I suspect the problem is doing with Web browser, If one user using browser and switch to other user without logoff, it will freeze up when other using login.It seem working on following contion.
1. It seems ok when all users quit using browser,and it doesn't matter how many times you switch between users.
2. delete all other users and operate as only one user
I have a usb wimax wireless adapter. Some times it stops responding to commands and I have to detach and attach it again phisically. My question is: is it possible to do equvalent operation remotely, over ssh like in case with mounting/unmounting filesystems?

I'd like to be able to re-attach as well. Anybody know if this is possible and, if yes, how?
There are often times when the best way to launch an application is from the terminal, but it is a graphical application and after it is launched the terminal is useless.
Examples of places where a terminal is convenient are when a process starts lots of child processes and is also unstable; you can be sure to kill all of its children simply by using Ctrl-C at the terminal. Also it allows me to read program output and to set up the terminal environment to be optimal for the application (for example "unset LIBGL_ALWAYS_INDIRECT")
With GNU screen, I can get around the hassle of having a terminal window open by using something like the following in a terminal window:
Code:
screen
my_command
Ctrl-A d
and then I can close the terminal and the program will keep running. Then I just type "screen -r <Tab>" (the tab will get me my screen session if there is only one such session) in any terminal window, even a tty, and I can get the screen session back and use Ctrl-c or something.
So my question is, is there a way to do this automatically so that a launcher or script will start a screen session, inside that screen session start a process, and then detach from that screen session without me having to manually open and close a terminal and type the commands?
I have a program that creates and uses a shared memory segment. I am trying to find out how to detach and delete this shared memory segment when I hit crtl-C, and I still need the process to terminate.shmdt() and shmctl() have variables that are local to the main passed to them(shared and shmid)
Code:
//Prototype
void leave(int sig);
//part of code trying to use signal handling
if(signal(SIGINT, leave))

I'm running ubuntu 10.04 as a mythtv box and it works mostly fine. But occasionally the system will hang during booting and the last messages I can see are code...
So, I don't know. What is the problem? This system is supposed to run mostly unattended, I can't check all the time whether it booted alright.
So what can I do?
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

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?

iv looked on the wiki and tried what it says it doesn't work
My partner and I share the computer, so we are normally both logged in.
When we come to turn the computer off, one of us will log out then the other shuts down (to have a clean shutdown), but when either one of us uses 'Logout' the system just freezes, no response, nothing, have to turn the machine off via power button.
We can 'switch user' fine, and everything else appears ok but log out fails, I did try reporting a bug on this, but seems to have got taken over with people with dual screens / SLI cards, taking it over and its not the same thing.
I get the 'impression' its a graphics driver issue, I'm using the 'recommended' Nvidia driver (am at work and can't remember which version sorry).
I'm putting this in general, because I'm not sure if many of the specifics are relevant.I have an everex cloudbook which I purchased from eBay with hardy herron on it.I finally got around, today (I've had it for a year), to installing netbook remix 9.10 with a usb key I had also purchased from eBay.Now, during the upgrade (using update manager) from 9.10 to 10.04, the system appears to have frozen.(desktop frozen, no response to keyboard or mouse).Now, I'm not sure if something could still be happening inside there, and if it would be a good idea to let the machine site overnight before rebooting it. Frankly, it happened once already, and I rebooted, and update manager just took up where it left off once I logged in.
I have not determined what's causing these freezes. It's not a new machine, of course (everex, afaik, doesn't even exist now), so maybe netbook-remix is too taxing on the hardware? I installed xfce to get away from the bloated netbook-remix graphical menu garbage, which did seem to allow the system to run faster. Anyway, the real question here is, while the interface appears frozen, could the upgrade still be developing under the surface? (I hear a fan running in there. There is no hdd to spin, but flash memory, so I don't know if the fan is any indication of internal activity). Would you wait to reboot it? (update mgr indicated 4 hrs remaining to upgrade, in the installing upgrades phase, not downloading, appears it froze during "Running post-installation trigger install-info"). Or just reboot it and see what happens (get update mgr to start again?)? The system never froze on me with hardy. It was pretty quick and snappy, in fact.
Running Ubuntu 10.4 32bit (only) on my system with ati graphics card. I just ran a software update, and I believe a new kernel was installed. When I rebooted, I saw the "Ubuntu" loading screen, but then the system froze up and the screen went completely blank. Thinking it was a graphics issue, I tried to press escape to get into the grub bootloader. However, when I pressed escape at the proper time, the system just rebooted.
Thinking that grub was broken, I used a live cd to purge grub from my system and re-install it. When I rebooted, I got the same initial problem: I get the "Ubuntu" loading screen, but then the screen goes black and the system appears to be frozen. Again, if I press escape to try the grub bootloader, the system just reboots.
Nothing too major here but today I had a few programs open and was doing a bunch of things and suddenly the system froze.
I am on 10.04 LTS -
Are there checks that I can do to see if everything is ok?
I had to turn the power off and re-booted and everything is fine, or rather, seems to be 100% fine - but more out of curiosity Id like to see if there are some checks that I can do.
I think that ubuntu creates a log of activity if I am not mistaken?
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).
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'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!)
View 9 Replies View RelatedI am a convert to OpenSUSE having recently ditched Windows. I really like the latest version of OpenSUSE but keep experiencing this annoying system freeze every 20 minutes or so. I get absolutely no response from the keyboard, although I do have the mouse working. However the end result is ALWAYS a cold boot
I am running SUSE on a spare machine as follows:
DELL Optiplex GX270 standard machine with integrated peripheral devices etc. Chipsets are all up to date and the hard drive is performing without fault. 1.25 Gb Ram
I am running Ubuntu 9.10 and trying to use OpenOffice 3.1. If I run OpenOffice, after 10 minutes or so, the whole computer freezes. Even if I have shut down OpenOffice it still happens. Only answer is to turn computer off and on again. I read some other people's posts listing the same problem and as a result uninstalled Open Office and then installed it again. I also uninstalled Compiz. Neither of these seem to be the solution. I have just installed Lotus Symphony and there are no problems with freezing and so the issue is definately with OO and Ubuntu.
I then on further advice uninstalled the bundled Ubuntu version of OpenOffice and installed directly from the OpenOffice website. The problem still remains. Next thing I tried was to uncheck autosave feature. The above problems only happen on my desktop. I also have an ASUS EEE Netbook running Ubuntu 9.10 Netbook remix. This is fine - the problem does not seem to affect the netbook. I would really like to continue to use OO - I like it a lot. Unfortunately this freezing issue is making it unusable.
[I'm not sure if this is the right forum. This is the closest I've found]. I've installed Ubuntu 10.04 LTS (dual boot with Windows XP SP3). After Ubuntu starts, it takes about 10 seconds, and the computer halts. No screen/mouse/keyboard activity. If I start Ubuntu under Recovery Mode, with failsafeX, it doesn't happen.
In the Windows all is fine. What did I wrong? [My CPU is: Intel(R) Pentium(R) Dual CPU E2140 @ 1.60GHz, if it matters...]
I've recently installed 10.04 LTS on a desktop PC so I can use it as a Zabbix monitoring machine.
I fresh installed and all seemed to be well but after a few restarts the system suddenly refused to boot anymore. The BIOS splash screen comes up and then a cursor blinks on the screen for a couple of seconds and then... nothing. The keyboard and monitor both go unresponsive and nothing happens.
I can hear the HD spin up and it isn't making any weird noises. Also, booting from the CD works and I can see and work with the HD so I'm not convinced that this is the problem.
In fact, I actually did a fresh reinstallation of 10.4 onto the machine and started from scratch. Again it ran fine for a few hours while I was setting Zabbix up. After a couple of restarts, again the freeze on boot.
I ran a HD scan and everything seems fine. I've also switched the HD over to the second IDE connection in the box just in case...
Does anyone else have this problem? Is it a bug? Any ideas on how to workaround it? (Short of going back to a previous Ubuntu version)
When I do some copying of files, or any background disk activity with file reading (transcoding a movie, uploading a big file to FTP, virus scanning) all computer becomes so slow, that I hardly can move my mouse, not to mention any productive use. I have SATA HDD, and Intel Quad CPU. I took measures to be sure it is not CPU or memory resource problem. Gentoo, Fedora, Windows don't freese that much on file reading. It is not a filesystem problem, or HDD, cuse I tried exactly this partition with other OSes.
Nice has a minor effect, but is is not enough, and I can't always start Nautilus with another nice level when I want to copy a file. What can I do to lower the priority of disk operations globally, and make apps to share disk thoughtput equally, not the one to occupie the disk until it finishes?
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'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 .
I built a new system for 11.04
Intel i5
ASUS P8H67-M LE motherboard
4 gigs of ram
2TB Hard drive
DVD writer
I am getting system freezes, but the mouse pointer still responds (moves arounf).
I suspect that it is the Sandy Bridge video. The freeze is preceded by video corruption.
How do I proceed to get this resolved and report the errors to the development people?
I frequently (i.e. after 10-20 minutes of use) get a complete system freeze when using LibreOffice Calc 3.3.3, on Ubuntu 11.04. At the time, I have an *.ods file open, and the freeze happens at various times, for example just after pressing the Page Up button. After the freeze occurs, nothing responds, not even Ctrl+Alt+F1, and I have to force power off my laptop.
how to debug this problem, as there's no error message, no error log (that I know of??)..
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.
After last kernel update (2.6.31.8) when I try to connect to access-point my system freeze.
I use realtek network card (rt2860sta module).
