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. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to a duplicate bug report (644740). https://bugs.launchpad.net/bugs/946899 Title: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
