Comment 221 for bug 1140716

I installed this one today from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.1-raring/ but still got a GPU hang:

Linux marc-work 3.8.13-03081301-generic #201305311535 SMP Fri May 31 19:36:22 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Jun 7 15:15:29 marc-work kernel: [18343.103877] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
Jun 7 15:15:29 marc-work kernel: [18343.103883] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state

Attached is the i915_error_state file.

But this time I could at least switch to the console and back to X and it worked again. Before this i used the current image in raring (3.8.0-23.34) and then the whole system hung, I wasn't even able to go to the console.

This is a Lenovo T520, lspci output:
