Full report (dmesg, cpuinfo, version, /proc/dri/0/* etc...) mainline kernel
3.8.rc6 + UXA

First symptoms of the bug in 2.8.rc6 with UXA acceleration using latest intel
drivers. Desktop freezes for several seconds (5-10) but recovered after that.

dmesg does not show "GPU Hung", but bug starts with several "*ERROR* Timed out
waiting for forcewake to ack request." and seems to recover after a
"[sched_delayed] sched: RT throttling activated".
