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

[Stan Schymanski]

For completeness, below an example from the syslog under Kernel 3.8.2
(again needed emergency reset). I also tried Kernel 2.6.38-13, which did
not result in the same "GPU hung" message, but lots of other crash
reports, so I gave up quite quickly.
