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

[AntonioK]

Same problem with Kubuntu 12.04.2 LTS / 3.2.0-40-generic / x86_64.

i915.i915_enable_rc6=0 option doesn't helps.

I discovered that hangs occurs more often in first minutes after
starting X, and if there are few hours passed without problems, hang
likely won't occur untill reboot.
