I'm seeing this bug, or something like it, on an older chip (G965, desktop version):
Feb 19 22:05:56 muttonhead kernel: [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung Feb 19 22:05:56 muttonhead kernel: [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state Feb 19 22:05:56 muttonhead kernel: [drm:kick_ring] *ERROR* Kicking stuck wait on render ring Feb 19 22:05:57 muttonhead kernel: [drm:i915_reset] *ERROR* Failed to reset chip. after which the mouse pointer sticks in one spot (with most other things working), and then when I shut down X, the console fails to appear, requiring a reboot. Not knowing that the given file path was under /sys/kernel, I failed to capture the error state, but will do so next time this happens (which is maybe every other day). This is with a 3.7 kernel (Gentoo); before 3.7, the driver was stable. I don't know what the 'generation' numbers in the driver mean, but I'm guessing that generation 6 is later, so many of the suggested fixes would not make any difference on this machine. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1041790 Title: [sandybridge-m-gt2] GPU lockup IPEHR: 0x0b160001 IPEHR: 0x0b140001 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1041790/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
