It's been freezing on me like you wouldn't believe today, and I think it has something to do with the load put on the CPU by various sites. The trouble is, I need to access a few of these sites to do my work. WordPress is one of them. I've had to restart the computer five times via SysRq keys since when these freezes happen, I can't Ctrl-Alt-Backspace out of it (even with zap enabled) and I can't bring up a terminal or Alt-F2 to kill process. I can't switch processes, windows, or anything. Firefox just sits there and laughs at me as I threaten to bust the screen in half.
And the real funny thing is, people actually say this is a better browser than IE. I never had these problems on Windows.What can I do to stop this? Do I just have to switch to another browser?
Where a CentOS 5.3 installation on a server randomly restarts. The problem is that I am not able to find a viable solution. I have updated the system to the latest available kernel, but to no avail...
The output I see in /var/log/messages when the restart occurs is very similar everytime:
since the launch of Natty I have been having stupid reboots randomly happening, no warning or otherwise occurs just a full reboot. This only seems to happen when browsing (FF or Chrome) and I have disabled every one of my addons and done the usual checks - baffled I am...So I had this with the upgrade I did on launch day, so naturally I did a full wipe and fresh install. Same situation - personally I cannot deal with this happening all the time so I went back with another full wipe to Maverick and all has been well.
Anyway I thought leaving this a few weeks would mean the community would have seen and squashed dealbreaker bugs so I re-installed yesterday, today the crashes came back again so I throw myself to your wisdom - anyone else seen this, know where I should be looking for ideas? My logfiles don't show anything prior to the reboot as an error.In all honesty I do not want to go back to maverick and cannot believe that Ubuntu have released such a bug riddled distro.
I'm getting very random full system freezes with F13. The keyboard stops responding completely. Sometimes the mouse (and the mouse only) still works. I those cases, I can log in via ssh, kill kdm, and everything goes back to normal until the next freeze. However, in most cases, I have to do a hard reboot. Sometimes the system goes on for days without a problem, and sometimes it freezes 10 times in a day (It's in one of those days that the bug-screen saved me from flying out the window). I also had this problem on F12. I'm not sure if its video-driver related as both nvidia and nouveau experience this behaviour. In fact, I'm not at all sure what the cause may be.
I am in the process of trying to move my files from a windows 2003 install over to fedora 12 using the Fedora 12 x86_64 Live image.
After some initial problems with burning the ISO image (had to enable disk-at-once to get rid of I/O buffer errors). And a GPF in the xor_sse2 module while building my software raid 5 arrays (forced to reboot, unable to stop or restart the array) I finally managed to create a single LVM volume group ontop of it all.
Initially I ran some tests on the raid volume and wrote a large 100GB file filled with zeroes all over it to be sure that it was functioning normally. After that I proceeded to copy files over from the NTFS volume to the LVM volume. which resulted in lots of errors on my terminal and complete loss of the entire filesystem. Even a simple ls -l / resulted in "Bus Error" although the system still kept running for a few seconds, until it finally froze and spontaneously rebooted. Since then I ran memtest to be sure my memory is fine, and tried alternative ways of mounting the volumes, and copy methods. Each attempt resulted in either a complete freeze or instant reboot. After 6 reboots, I managed to copy 20GB out of 490GB. Obviously this will take forever this way.
/var/log/messages is unhelpful. There are a bunch of cryptic messages regarding ATA bus errors (mostly CRC errors it seems) and soft resets when the LVM volume get mounted, but everything functions fine until I touch the NTFS volume.
Here are some of them:

HP Compaq 6820s: During the installation of F14 I noticed that the system freezes for a while every few seconds. The installed and rebooted laptop behaves the same way. Disturbing repeated messages in var/log/messages:

I've been using Ubuntu for a while now, and ever since I installed 10.10 (I did a clean install) I've been having problems with the computer completely locking up... nothing is responsive. I've not had this problem on any prior Ubuntu version. The problem started after I installed the updates for ubuntu... I have a hunch that its either the nvidia driver i installed or the latest kernel thats causing the problem. I'm using the proprietary driver for nvidia and my card is a GeForce6100 nForce 405... the kernel 2.6.35-22... as you can imagine its quite annoying having the computer lock up.. P.S.- the freezes aren't exactly random, they happen generally when I'm using high CPU %'s (e.g. when i import all my music at once to rhythmbox and playing spring rts)
At random times (approx. once a day), my whole ubuntu/gnome interface freezes. mouseover-animiations (for example on the icons in the taskbar) keep working, but clicking doesn't do anything anymore. On the keyboard, tab and arrows keeps working, but most other keys don't do anything. The only option seems to be to reboot. After that reboot everything is fine again (for a while)
Once the freeze happens, it freezes both the standard ubuntu panels but also the program I have open at that moment. It doesn't seem to be connected to a specific program I run.
Is there some log, or anything else that I can use to figure out where these freezes are coming from?
I've been using rTorrent for a good two years now, and it's been running smoothly until about 6 months ago when random crashes and freezes would occur, between once per day and once per week. (I think it freezes if I run in screen, and crashes if I run it directly.) I've updated both rtorrent and libtorrent, updated cURL, and searched the internet near and far for a solution. I finally got this output (pastebin) after a crash today. I'm not sure how far up it goes, mainly because I'm not sure how I can scroll up the terminal window, and syslog doesn't seem to be of any help. Bottom line, I have no idea what rtorrent/libtorrent are doing, and random crashes are becoming very frustrating. For what it's worth I have a very large library (2000+) of shared files. Using version 9.04
I installed Ubuntu Lucid on my computer a few weeks ago (fresh install, formatted). But recently I've been having some problems.
This is about the 4th time it happens. When I randomly open a program, sometimes the whole computer will just freeze. I can't change to a terminal window with Ctrl-Alt-F1,2,3,4 or anything. I can only press the Reset button on the computer case. This is frustrating because I already lost ALL my firefox settings and addons and I don't want anything like this to keep on happening.
The problem was: *drumroll* the POWER SOURCE.
Apparently the voltage was having little drops and this caused all the hardware to freeze. This caused the system operation to be WORSE after I bought the new graphics card (since it was bigger and needed more power). I bought a new powersource and installed it and it seems everything is alright now.
I currently have Windows 7 Ultimate 64 running on my Asus laptop. I decided to install Ubuntu 10.10 along side Windows, as I will need it for work. It was installed via side-by-side and re-sized the partition
The installation of Ubuntu was flawless and works great, but now when I boot to Windows, its will randomly freeze, sometimes in 1 minute, sometimes within 10 minutes.
The only way I can solve this issue, is to either perform a disk scan from windows or restore the MBR.
The disk scan works, and Windows run fine, although If I boot Ubuntu again, run that for awhile, then boot windows again the problem returns.
Restoring the MBR works as well, though without a dualboot, its useless
I have also tried EasyBCD and replaced GRUB with Windows boot manager, though same problems.
i am, many people out there using Ubuntu 10.10 (or 10.4) have been experiencing seemingly random freezes. Whereby the system freezes and responds to absolutely no input. If you have been having a similar issue perhaps you could post in this thread and we could try and establish some commonalities. Perhaps its hardware, software, drivers or some combination. I have a Dell Inspiron 1300, with a Pentium M 2.10ghz CPU. I have experienced freezes with and without Compiz running and even in Openbox sessions.
I have an HP dx5150 with Ubuntu 11.04. I recently added 2 new memory chips (total 4) with the same specifications as the originals. The memory is recognized by the BIOS and Memtest returns no errors. The computer boots normally and functions normally for an hour or so, and then freezes. When it freezes it does not accept any input and the screen gets displays a bunch of small green or purple lines. Here is the output from lshw:
i've been running Kubuntu 11.04 for a couple weeks now and trying to transition away from windows but i have had this problem with seemingly random system freezing and crashing i run kubuntu 11.04 64bit on a dell studio 1558 with a core i5, intel hd graphics, and 6gb ram.
my laptop after awhile will just freeze and all i can do is a hard reset, sometimes the screen will go black with a bunch of text, but i think that only happens when virtualbox is running b/c i can sometimes get back to the desktop, but it will freeze nevertheless (i run win7 in vbox for certain things i need like itunes and office).. i do notice that my laptop is getting pretty warm, but i don't know if that's related b/c it always did under windows
I got Ubuntu 11.04 on my USB and I booted from it for the first time, worked fine. I went back and it started to flicker and freeze then come back and the rez was stuffed.
I had Linux Mint installed and it became subject to random freezes. The system was never under any serious strain at the times that this occurred. I went to the Ubuntu forums and discovered that this is a relatively common problem with Ubuntu and that there's no fix available. I tried almost all advice offered there, without any remedy. These included disabling Flash, Java, Compiz, Nvidia drivers etc etc.
I decided to try another distro. Since then I've had random freezes in Suse, Sabayon and even with a Fedora live disc. Oddly enough, I never have this issue with Win 7 (I dual boot). If this is a hardware problem, why does it never occur under Win 7? If it is, as I suspect a hardware issue, how can I identify the source of the problem and resolve it?
I'd been using karmic for ages with no probs. I did a fresh install of lucid when it came out and installed compiz and cairo-dock. Rather annoyingly my computer started to completely freeze. I couldn't get a shell up, I couldn't ssh from another machine and the sysrq keys didn't work (the fan picked up speed almost immediately). The freezing didn't seem to follow any pattern and wasn't happening when accessing the dock. I decided to disable compiz (and cairo-dock) to see if this helped. It did! I reintroduced compiz with no problems, but as soon as I introduced cairo-dock, I started to get the same problem.
I've not been able to find anything in the general logs to give any clues. ubuntu lucid
1st post @ LQ. Ubuntu user since 2007ish. Lots of PC experience... now vexed by upgrade from 9.10 Karmic to 10.04LTS Lucid.
The problem: random freezes whenever I boot into Lucid as user through usual Grub menu. The freeze sequence is: 1- screen stops, 2- mouse pointer freeze w/ no effect on click but moves freely and keyboard is useless, 3- screen blacks out for about 30 seconds and then returns but is unusable and 4- constant HDD activity for about 5-10 seconds. I have waited several minutes for a recovery of some sort but no dice. I reboot via on/off or reset button. Ubu deletes 2 inodes and then I'm off and running again.
If I boot through the recovery console there are no problems at all. The recovery console sequence: 1- select recovery from Grub menu, 2- at recovery menu select drop to root command prompt, 3- give root password, 4- enter 'gdm' at console prompt, finish boot up in my only user desktop (not root.)
I have not been able to find any log files that show an error message, but I'm not so tech oriented that I would necessarily know one if I saw one. Through many hours of browsing posts describing Lucid problems @ UbuntuForums (one of which has over 1,000 responses) I have found my '.xsession-errors' file (attached) is full of data.code...
My system just freezes randomly. It happens about once a day, which is really often imho. It usually happens when I'm watching a video in fullscreen and it suddenly stops. I can't alt-tab or escape out of fullscreen, my mouse doesn't work and the keyboard is unresponsive. I'm forced to restart by pressing my computer's power button. This happens in both vlc and kmplayer and it also happened a few times when i was not watching a video. I was just on firefox, browsing the internet.
I'm running Ubuntu 10.04 Lucid Lynx Desktop Edition and most of the time I get these random freezes and then I have to turn off my computer and reboot it back on. It's getting really annoying because I am constantly downloading huge packs of data and it freezes and then I have to start re downloading...
I'v been trying to install Ubuntu (and actually all other dists of linux (in hope of succes), but running ubuntu on my other machines and prefer it) on my old laptop. Laptop Acer Aspire 1312XC. Have just run a 24 hour RAM test it turned out ok. Have tried with other RAM blocks in aswell. The install freezes at random points in the installation. Mainly when trying to copy files to the hard drive. The only thing i've succeded in installing was Ubuntu server and windows XP. I have tried with ACPI off and all the other special atributes. No success so far.
I am stumped. I get random "freezes" for like 20 seconds, then back to normal. Then again the same thing randomly. I thought it was my hard drive...replaced it, reinstalled 9.10 and same issue. Thought it might be the memory...nope!, thought it might be my motherboard, tried to update my bios and it froze and now I can't get in to my bios at all. I bought a new motherboard and did a fresh install of 9.10 and same problem!!! I took my hard drive out and put it in another computer and it ran the same ruling out hardware issues all together.
I'm on Fedora 13 (64 bit) and using tvtime (latest version 1.0.2-13.fc13 installed via yum) which I've managed to get to work with my old WinTV card (bt878 chipset I think) by having it start with its mixer-device set to "hw:0/Line" (the WinTV card outputs the sound via a cable to the Line In socket of the soundcard).
This all works (I can control the volume in tvtime using the left and right keys) except that the volume resets to zero every time I restart. tvtime remembers all my other settings (and the previous volume is even saved in its config file) so I think the issue is related to ALSA/PulseAudio resetting the appropriate mixer (Line In on the internal sound card).
However, I can't find which mixer tvtime is accessing. In 'Sound Preferences', changing the Master Volume affects the sound from tvtime, but none of the other mixers seem to be related to it (and tvtime doesn't appear on the 'Applications' list). I've also tried finding it in alsamixer, which gives me a choice of 'default' (PulseAudio), 'HDA Intel' (the internal sound card) and 'Brooktree Bt878' (the TV capture card) and again the 'Master' and 'Front' mixers do affect the sound, but are not the mixer that tvtime is accessing.
I know this is a very specific and minor thing, but it's a bit annoying seeing as I've got everything else set up near-perfectly.
Or alternately, as a workaround, is there an easy way of creating a script to lanuch tvtime and send some volume up commands (right arrow key) the first time it is run after a restart (but not the times after that)?
I have a problem with scrn and keyboard freezes. This time it only threatened to crash, and I've noticed something in /var/log/ mssge that might lead to a solution (if I understood it)
Apr 5 06:42:04 Den-mint kernel: [ 233.209761] EXT4-fs (sdc1): warning: mounting fs with errors, running e2fsck is recommended It's imediate context is below.
Every time I try updating my system to the new Debian stable, I end up with a system that no longer recognizes my burner and even though autofs was not updated, it is restarted and all of a sudden there's no map for it. This usually takes nothing more than updating Amarok to "stable", because libc6 must be updated. I've tried updating different programs and this is the one factor that remained the same when the autofs no maps issue cropped up. I am considering trying again. But testing the system upgrade on another partition, so I can get it right before using it on my "real" system.
Last time I made an attempt, I was able to make my burner and floppy drives visible under "computer" by adding both to the fstab file, and was even able play DVDs, CDs and floppies but the K3B burner would not recognize the burner and said hal was used to detect, but HAL was not updated -- I'm absolutely sure of this. The other burner program (Gnome Baker) would at least recognize and even named my burner, but could not burn a disk. I did update HAL afterwards, hoping to help the situation, but it improved nothing and may have made things worse. When I rebooted the next day I had no disk access whatever.
As I mentioned in the title, I believe upgrading to libc6 led to the trouble. Don't understand why. When I upgraded from old oldstable to the new old stable last year nothing bad happened. Would skipping over new "stable" libc6 and going for the new unstable work? If I could just solve this one problem, I could easily upgrade Dreamlinux 3.5 from Debian 5.0 to 6.0.1. That's where it was when I upgraded most of the system, before recognizing there was a disk recognition and mounting problem.
We are having a cluster with couple of disk servers, compute nodes and a head node. Disk server is nfs mounted on all the compute and head nodes. The problem is that if any of the disk servers hangs, it freezes rest of the cluster too which is dangerous. Ideally, cluster should not care about the hanged server and run without any problem except files from that server is not visible. Is there any way I could avoid the problem of freezing cluster because of one hanged server?
I few days ago I bought a mobile broadband, with dongle model Huawei e1820. I have no problem connecting to the internet. The settings in network manager are correct. But when I use the modem with high traffic for a while, like streaming, the speed gets slower and slower until finally the modem shuts down and restarts itself. After the modem restarts, it connects to the internet again, but now the speed is terrible. And if i continue using high traffic it will restart itself in a matter of minutes. But if I plug it out and don't use it for a while, the speed is back to "acceptable". For a while...
I'm using fedora 15, and have also tried it on Ubuntu Natty with the same result. Reinstalled usb_modeswitch. configured usb_modeswitch with all the guides on the web. No results.
