[Bug 946899] Re: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

[Anthony Rogliano]

This still happens on Ubuntu 13.04 patched as of 7/26/2013 on a Lenovo
T420.

kernel: 3.8.0-26-generic #38-Ubuntu SMP Mon Jun 17 21:43:33 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
lspci: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

Please prioritize as it's extremely frustrating. I can't seem to easily
capture the error_state because it's cleared out upon reboot (unable to
switch TTYs etc).
