Thanks for the hint. I tried the 3.8.13 kernel on x86_64 with a Lenovo X220.
I can still torture out hangchecks with 3.8.13-03081302-generic #201306071405 SMP Fri Jun 7 18:06:32 UTC 2013 x86_64 by running three glxgears and youtube at HD resolution, e.g.: [ 787.335798] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung [ 804.309281] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung [ 804.317252] [drm:__gen6_gt_force_wake_get] *ERROR* Timed out waiting for forcewake old ack to clear.

GPU hung However, the drm seems to recover on its own for the most part, like the 3.10.x kernel. So that is a definite improvement. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1140716 Title: [regression] 3.5.0-26-generic and 3.2.0-39-generic GPU hangs on Sandybridge To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1140716/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
