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

[Stan Schymanski]

After half a day of working on 3.8.13-030813-generic, got the
"[drm:i915_hangcheck_hung]" again. At least it was sort-of recoverable,
as I was able to log into another tty and backup i915_error_state
(attached). Hope it helps someone for diagnosing the problem. When
returning to tty7, Screen was still flackering whenever I moved the
mouse, and it didn't seem to respond to any clicks, so I had to logout
by CTRL+ALT+DEL and then I could log back in without problems.
