When I boot with i915.i915_enable_rc6=-1 I'll get GPU hangs in when switching between windows in gnome-shell. When I boot with i915.i915_enable_rc6=0, I cannot reproduce the hangs. I tried to bisect between v3.3 and v3.4 and the offending commit was simply enabling rc6 by default, so I'll have to redo the bisection with rc6 enabled, but I'm not sure if I've ever had rc6 stable on my system.

Hopefully we can source a system and reproduce... My hardware configuration is - 2500K - ASRock H67M motherboard (http://www.asrock.com/mb/overview.asp?Model=H67M), BIOS 1.50 I don't think I've ever had a configuration where RC6 worked, I just didn't notice that it was broken because it wasn't on by default. What else can I provide?

Thanks for testing this anyway.

The computer is now packed and won't be unpacked for at least 6 weeks, so I can't check. Others with the same problem may want to check. The fact that Lorenz's motherboard is also an ASRock H67M is quite a coincidence if it's not actually related to the board.
