Ubuntu :: Random Freezes And Crashes On Kubuntu 11.04
Jun 28, 2011
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'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 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:
Code:
Dec 22 02:32:15 localhost kernel: ata6.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6
Dec 22 02:32:15 localhost kernel: ata6.00: BMDMA stat 0x4
Dec 22 02:32:15 localhost kernel: ata6.00: cmd ca/00:80:02:a5:fb/00:00:00:00:00/e7 tag 0 dma 65536 out

Ive been having some problems with a Compaq computer with Lubuntu installed. The problem is that Xorg crashes at random displaying a white distortion on the screen and it usually doesn't let me go to a terminal and i have to force a shutdown.
the same happened when I tried to install Ubuntu but worse. Another side effect is that lubuntu at boot up displays its logo in 16-bit colors and then goes to normal colors.
how can i diagnose the random crashes?

(Update 5/19: I can now reproduce the bug either booted normally or from the live CD)
I've got the strangest bug and no idea what is causing it. While web browsing, sometimes the OS will completely crash. The crash always goes the same way:
First, it shows some text on the screen too fast for me to read, but it looks like red ASCII bullet points followed by white text, both over a black background.
* SOMETHING SOMETHING
* SOMETHING SOMETHING
* SOMETHING SOMETHING
After doing this for about half a second, it enters some kind of loop. The top half of the screen alternates between black/white vertical bars and solid black, while the bottom half of the screen remains solid black.
The only way I've been able to get out of this is by pressing the power button, and doing so shows me the *buntu logo (currently using Xubuntu) and then turns itself off.
Here's why I can't figure out what's wrong:The crash happens in GNOME, KDE, and XFCE. I have since uninstalled KDE because I was just checking to see if it still crashed.
Both Firefox and Google Chrome cause the crash.
No other programs seem to crash this way; just the web browsers. I've played games and listened to music for hours with no problems.
Opening the same pages doesn't reproduce the crash. It happens randomly every hour or so.
Even simple pages (like tabs of JPEGs with no HTML) cause the crash.
This is a recent install from an Ubuntu 10.04 CD.
I was previously using Kubuntu 8.04 and had no issues.

Recently my Firefox 5.0 started to crash randomly. This morning, it crashed twice within three minutes. I believe that it crashes mostly during loading something (such as a new tab), but it can also just crash when nothing is being done to it. I can be reading one page of text and it crashes. When it crashes, there is a "Submit a report" thing. When I click Restart Firefox, it doesn't. What I can think of is the use of Flash-aid and the addition of a 4GB bar of RAM. I re-executed Flash-aid because 1080p full-screen was choppy (still is). I don't think it is a Flash problem since with Gnash, Firefox also crashes. The RAM bar is a Lexar 4GB DDR3 SODIMM 1066-1333MHz. All other programs run correctly. I have re-installed Firefox, Firefox-branding and such in Synaptic. Still crashes.

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)

I have no clue when it started. Since 10 days or so my computer crashes randomly when working in Ubuntu. Here are some facts: It can happen after one minute or several hours Every time, music is playing (MPD / PulseAudio), but my player runs mostly the whole time, so i am not sure if that's helping No specific action triggers the freeze, but i think a simple click is mostly involved When freezing the audio buffer is repeated every second or so The reset button does not work! I have to press the power button for 5 seconds to shut down the computer In Windows i did not experience any freezes, while i am doing hardware intensive stuff like gaming or audio processing
My Hardware:
CPU: Intel Core i5-2500K
MB: Gigabyte GA-P67A-UD3P
GFX: Gigabyte GeForce GTX 560 Ti Overclock
RAM: G.Skill RipJaws DIMM Kit 8GB PC3-10667U
SSD: Crucial RealSSD C300 128GB

About 1-2 times a day (3 today and it's just 9 AM here...) Gnome 3 decides to just not care about me any more, crashes and logs me out. No warning, no error on screen, just some black screen with text (like when shutting down the computer and it's stopping services) which lasts half a second, then back to the login screen.
Any ideas what might be wrong or where I could find some logs to post them here?

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.

As per the title, really. I've upgraded to 11.04, ran updates, but I can't stop LottaNZB randomly crashing out. It will be running fine one moment, then 'zap' it disappears. I've tried going through the apps running at the same time, and there doesn't appear to be any pattern. In fact, I've left it running with nothing else open and have returned to a computer with no running apps. Sometimes, however, it will run fine for several hours, completing all of it's downloads, although this is pretty rare. LottaNZB's logs appear to wipe after a crash (unless I'm missing something) so I'm none the wiser why it happens. Has anyone got any ideas what to try next? It ran faultlessly on Ubuntu 10.x

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 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 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 seem to be getting a lot of firefox crashes. I was actually able to reproduce it every time by typing "S02" into the search bar...not sure why. Here's the backtrace. Edit: Odd, it also crashes when I enter s02 into my history search box...

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...

Got a new Lenovo T500, slapped 9.10 on it. Set of programmes is exactly as on my previous IBM T42, but every so often I get a random crash. No errors, just a complete freeze with a "underscore" cursor in the top-left of the screen.I think / suspect it may have something to do with Transmission running, or perhaps the recent kernel update to 2.6.31-17.Anyone else had anything similar? Maybe on a T400 or R60 / R61 / T60 / T61?

ecently (since upgrade to Ubuntu 10.10) being having problems with Amarok randomly crashing.There doesn't seem to be any pattern and it normally just disappears and music stops. Occasionally it comes up with the KDE crash tracker but it can't retrieve the debug information (although i do have amarok-dbg installed, not sure what else i need for that to work though)Anyway i have run it from the terminal and this is the output i got towards the end:
Code:

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?

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.

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 got a new desktop and figured this would be a great oppurtunity to update to 11.3 (from 11.2) while migrating files.. However I have had lots of problems with it, right of the bat. My first installation got messed up right after it was done, so I had to redo everything. Now the system boots up all fine but I am experiencing crashes every once in a while. By crashes I mean nothing works; the system monitor graphs freeze, the clock freezes, system doesnt respond to key strokes. The only remedy is then to "force an unexpected reboot" (ref: IT Crowd). I have a feeling that it has to do with Yast or something related to Yast, as it is the only common denominator between the crashes so far. However the system doesnt crash everytime I start Yast so I cant really say anything conclusively..
I have also realised that when I attach a secondary screen the graphics get kinda screwed as well.. if that makes any sense... Here are my system details: Dell Vostro Desktop with Core i7 64bit processor
8 x 2.8Ghz
6gig ram
graphics card: GeForce GT220
What could be the problem here? btw let me know if anyone wants to see logs from /var/log/messages

I just upgraded my Debian Wheezy XFCE 32-Bite to Jessie.
Now some strange freezes occur. After 10sec - 3min after login the GUi freezes and the screen gets blurry and some "lines" appear.
I never suffered from this bug under Wheezy. What could be wrong? Some conflict with the X-server?
