I get the following messages after login and start a terminal (urxvt):
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
Sometimes the hole system freezes and I have to hard shutdown the system.

It's the same pattern of hang as bug 43144. Just to test my sanity can you also try to reproduce with fbc disabled (because that resolves a similar hang on my machines). And we may as try with rc6 and semaphores disabled for completeness.
