    Ubuntu 9.04 crashes constantly on my ThinkPad X61 Tablet, with no apparent cause

    Ever since I upgraded to Ubuntu 9.04 ďJaunty Jackalope,Ē my ThinkPad X61 Tablet has been crashing constantly, generally at least once every day. I would really appreciate your help with this stubborn and seemingly irreproducible problem.

    IMMEDIATE SYMPTOMS

    When my system crashes, it goes down hard. Everything freezes up. The graphics are frozen in place. The mouse cursor will not move. If there is any sound playing, it will become stuck (the very last snippet will play over again, endlessly). If I try to SSH in from another machine, the operation will time out. There are no flashing LEDs (Caps Lock, etc.) that would indicate a kernel panic, and Alt+PrtSc will not work to shut the system down. The only option is to turn the machine off manually.

    LOG FILES

    The logs will show _nothing._ This is what is the most infuriating. Time and again, Iíve checked the logs and found nothing that isnít completely unremarkable. In every case, bar none, the last message in each major log will be something both entirely innocuous and not matching up with the time of the crash, often by a difference of minutes. (I always know the precise time of the crash because I set my GNOME panel clock to show seconds, and it will freeze up along with everything else during the crash.) Most common is the Network Manager roaming messages that dominate my logs.

    The _only_ evidence that something went wrong is _thoroughly_ bizarre. My X.org logóXorg.0.log.oldówill have a _different mimetype._ Instead of ďtext/x-log,Ē it will be ďapplication/x-trash.Ē However, if I open it explicitly in a text editor, there is no problem, not even any binary junk in the file. It will be, once again, completely unremarkable, and reveal nothing about the cause of the crash. (Keep in mind that the mimetype change doesnít happen until the failure itself. While running Ubuntu, my X.org log, Xorg.0.log, will be logging events just fine, and its mimetype will be the standard ďtext/x-log.Ē) (I should note that this problem could be unrelated; I havenít checked to see if this happens when X.org exits ďnormally.Ē I suppose I should do that, now.)

    THINGS IíVE TRIED

    Iíve tried to isolate the problem. Iíve tried using the 2.6.30 RC5 kernel and the X Updates PPA, and the crashes will still happen. Iíve tried using the old Intel graphics driver, compiled for Jaunty, with no luck. Iíve successfully changed my xorg.conf-based Wacom configuration to a proper hotplugging-based one, and though it brings me peace of mind (and xorg.conf is now at its default, nearly-empty state) it hasnít solved the crashing.

    Iíve also tried using Apport to collect crash reports, with no luck. (Obviously, I imagine itís hard for Apport to create a crash report for a crash that brings down the entire system, but it was worth a try.)

    WHAT DO I DO?

    This has been incredibly trying for me! I donít know where the problem is, so I donít know where to file a bug. All logs seem to be clean of evidence of something going wrong, so I donít know what avenues to go down. The system seems blissfully unaware of its own problem.

    Iíve Googled my brains out and havenít found anything. Iím not sure this is a common problem, even with my particular model.

    Itís heartbreaking for me because I do art, and Iíve been working on digital painting projects of the kind where saving can take a full minute or more, so saving constantly is never an option for me. So, Iím determined to solve this problem, but Iíve run out of options on my own.

    Iíve attached the output of lspci -vvnn to this post. I donít have an Xorg.0.log.old that pertains to this problem, because I had to restart X just now due to a different problem (argh), but Iíll post one once I have this problem again (wonít be long, I imagine.)

    Any advice, help, thoughts, or anything else relevant to this problem would be greatly appreciated! I think Iím at least fairly Linux-literate, so I should be able to obtain any other information on my system that you might request. Thank you!

    Thumbs down Re: Ubuntu 9.04 crashes constantly on my ThinkPad X61 Tablet, with no apparent cause

    I have the same problem on a Acer Travelmate 6292 and after yet another total crash last night I've been searching for some fix to the problem. I can't relate it to anything specific - it usually locks up when using OpenOffice.org, but last night it crashed while running DSL in VirtualBox. When Ubuntu locks up the system is totally unresponsive and I have to do a hard shut down by pushing the power button - and of course lose any unsaved data in the process. I suspect my integrated Intel graphics card has something to do with it, but I'm far from sure. However, Ubuntu is running smoothly on my Asus eee pc 901 (the UNR flavor).

    I'm using my Travelmate and OpenOffice.org in order to write my master's thesis and quite frankly I can't take anymore of this.. I can't afford to lose my work whenever Ubuntu decides to crash, so I'm afraid the only remedy right now is to back up all my data and try a distro that can provide a more stable environment.

    Hi Cherry Cotton,

    It sounds like your aware of the Intel video issues with Jaunty and have dealt with it. You're also aware of the xorg-xserver bug which makes using xorg.conf a bad idea.

    So have you ruled out a temperature problem? I've seen several threads on high temps with Jaunty. If your temp does turn out to be up you could use top to find out if a process is responsible.

    Maybe the video thing is a red herring and you have a RAM problem. That's usually what causes the symptoms you're describing. Have you tested it?

    Re: Ubuntu 9.04 crashes constantly on my ThinkPad X61 Tablet, with no apparent cause

    Thanks.

    Okay, Iíve tried a few things. First, the memtest comes back with a clean bill of health. I left it going overnight, and attached is what it looked like when I woke up.

    Second, for the memtest, I shut the system off normally, and when I brought it up again I looked at the old X.org log. Sadly, it seems like the weird mimetype change is ďnormalĒ behavior; it does that even when you shut the system off without problems. Iíve attached the log, just in case itís relevant.

    Temperature might be the issue... the system runs hot enough often enough that I keep a temperature monitor in my GNOME panel. The difficulty, though, is that over time Iíve had this crash in all kinds of circumstances... sometimes I have my computer in laptop mode, sometimes I have it in slate mode rotated right, sometimes I have it in slate mode rotated left, and sometimes itís just sitting on my wooden nightstand during the night, and in each such case Iíve had this crash more than once. How Iím using the computer determines, generally, how much temperature becomes a problem... itís typically lowest when itís not in use, then when itís being used in laptop mode, then when itís being used in slate mode (when Iím typically holding it close to myself), and finally it runs hottest when I have it in slate mode rotated left, when the hot fan is pointing toward me (aaaagh!). (When the screen is rotated left, the buttons are at left, so this is the setting I use for doing art. Likewise, when the machine is at right, the buttons are at right, so I use that mode for reading. Iíve rigged the radio switch to change between rotation modes; Iíve spent way too much time customizing my PC like this...)

    Anyway, if temperature is the issue, what would be a good way to monitor my systemís temperature over time, to try and diagnose the issue? (Also, from now on, Iíll be sure to write down the temperature at crash time, since, after all, itís on my GNOME panel.)

    Thanks, yíall. More thoughts on this issue are quite welcome!

    (Itís also goodóand a little sadóto know that this issue is not specific to my ThinkPad machine. I wonder if we should contact some hardware-type experts...)

    (Oh! I should note one more thing. I did have crashing problems back in 8.10, when I first got this machine. However, those were garden-variety kernel panics, flashing LEDs and everything. I was happy to upgrade, hoping that the new kernel wouldnít have this problem. As far as I can tell, it doesnít; I just have new problems. Anyway, I donít think I ever figured out what was behind those kernel panics...)

    Re: Ubuntu 9.04 crashes constantly on my ThinkPad X61 Tablet, with no apparent cause

    I just noticed that my system, while sitting on the table doing nothing, was running really hot (80įC) and Tracker was getting its usual loop of errors. (I’ve been getting those Tracker errors in the past few days. That’s much less time, though, than these crashes have been happening, as they began when I upgraded back when Jaunty was a release candidate.) So, I shut down Tracker in the system monitor and the temperature went down to normal... hmm. Anyway, I’ll turn off Tracker and see if that makes a difference over time.

    Hi Cherry Cotton,

    Looks like you may have found the problem. And of course make sure the vents and fan are clean. Maybe blowing some canned air through things when powered down.

    No dice

    It crashed just now, while I was reading something. Tracker was turned off, and the temperature was at a mild 53įC.

    I really donít know what to do, now...

    Thereís a thread here about these weird crashes. I hope we can get this problem solved, soon....

    Unhappy Re: Ubuntu 9.04 crashes constantly on my ThinkPad X61 Tablet, with no apparent cause

    I have the same problem. Ibex worked just fine. After upgrading to Jaunty, I have had the same issues as Cotton has. I have a HP DV6000 laptop, with an Nvidia 7200 graphics card.
    I am sick of this issue and am planning to downgrade to Hardy Heron.

    Re: Ubuntu 9.04 crashes constantly on my ThinkPad X61 Tablet, with no apparent cause

    Hello Cotton,

    i hope someone still follows this old thread. I wonder if you were ever able to resolve the matter?

    Because i am experiencing the symtoms Cotton described so excellently. I am using a T42 thinkpad and Karmic Koala

    greetings

    jan
