There is udev code to detect gpu lockups which will capture i915_error_state in that case, but the general apport-collect script doesn't (we haven't needed it up til now, but probably can't hurt to collect). Since it sounds like that didn't happen here, it suggests you're experiencing something different than a "classic" gpu lockup. In IRC you mention seeing this:
<slangasek> $ sudo cat /sys/kernel/debug/dri/0/i915_error_state <slangasek> cat: /sys/kernel/debug/dri/0/i915_error_state: Cannot allocate memory -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1117563 Title: X hard lockup in raring, can't even switch VTs Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After an upgrade to raring, I've experienced a bug where firefox and X are each consuming a CPU doing nothing useful. When this happens, I can still log into the machine remotely with no problems, but the console is completely frozen. The X cursor doesn't move, unity doesn't respond, windows are not refreshing, and I can't even change VTs (from the keyboard, or over ssh - if I run 'sudo chvt 1', it hangs). It appears that X and firefox are both busy, but strace of firefox shows no output. kill -9 of the firefox process also has no effect (bug #1117499). There is nothing logged in dmesg or in the X log that seems relevant. After debugging this for about an hour, the firefox process spontaneously died, at which point X also stopped monopolizing the CPU; but the console was still frozen, A few minutes later, the VT switch request seems to have registered and I wound up on VT1. However, switching back to VT7 does not result in the screen being refreshed, and 'sudo chvt 1' again hangs. --- ApportVersion: 2.8-0ubuntu4 Architecture: amd64 DistroCodename: raring DistroRelease: Ubuntu 13.04 DistroVariant: ubuntu InstallationDate: Installed on 2010-09-24 (866 days ago) InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release amd64 (20100816.1) MarkForUpload: True Package: xorg-server (not installed) ProcVersionSignature: Ubuntu 3.8.0-4.8-generic 3.8.0-rc6 Tags: raring running-unity ubuntu Uname: Linux 3.8.0-4-generic x86_64 UpgradeStatus: Upgraded to raring on 2013-01-25 (12 days ago) UserGroups: adm admin cdrom dialout libvirtd lpadmin mythtv plugdev sambashare src sudo --- ApportVersion: 2.8-0ubuntu4 Architecture: amd64 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,imgpng,snap,place,grid,resize,regex,mousepoll,gnomecompat,unitymtgrabhandles,vpswitch,move,animation,expo,session,wall,ezoom,staticswitcher,workarounds,fade,scale,unityshell] DistUpgraded: 2013-01-25 08:16:10,776 WARNING no activity on terminal for 300 seconds (Configuring texlive) DistroCodename: raring DistroRelease: Ubuntu 13.04 DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:215a] InstallationDate: Installed on 2010-09-24 (866 days ago) InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release amd64 (20100816.1) MachineType: LENOVO 3249CTO MarkForUpload: True Package: xorg 1:7.7+1ubuntu4 PackageArchitecture: amd64 PlymouthDebug: Error: [Errno 13] Permission denied: u'/var/log/plymouth-debug.log' ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.8.0-4-generic root=/dev/mapper/hostname-root ro quiet splash --verbose vt.handoff=7 ProcVersionSignature: Ubuntu 3.8.0-4.8-generic 3.8.0-rc6 Tags: raring running-unity ubuntu single-occurrence Uname: Linux 3.8.0-4-generic x86_64 UpgradeStatus: Upgraded to raring on 2013-01-25 (12 days ago) UserGroups: adm admin cdrom dialout libvirtd lpadmin mythtv plugdev sambashare src sudo dmi.bios.date: 08/23/2010 dmi.bios.vendor: LENOVO dmi.bios.version: 6QET52WW (1.22 ) dmi.board.name: 3249CTO dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr6QET52WW(1.22):bd08/23/2010:svnLENOVO:pn3249CTO:pvrThinkPadX201:rvnLENOVO:rn3249CTO:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 3249CTO dmi.product.version: ThinkPad X201 dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.9~daily13.01.25-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.41-0ubuntu1 version.libgl1-mesa-dri: libgl1-mesa-dri 9.0.2-0ubuntu1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 9.0.2-0ubuntu1 version.xserver-xorg-core: xserver-xorg-core 2:1.13.2-0ubuntu1 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.7.3-0ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.1.0-0ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.20.19-0ubuntu3 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.6-0ubuntu2 xserver.bootTime: Mon Feb 4 17:31:16 2013 xserver.logfile: /var/log/Xorg.0.log xserver.version: 2:1.13.2-0ubuntu1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1117563/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
