hang dump

Running lightsmark 2.0 on SKL-U hangs the GPU quite frequently, eventually freezing the machine.

kernel 4.4.6 + i915 from 4.6-rc1
mesa 11.2.0-rc4
intel: git
xserver 1.18.2+fixes

hw is UMSK9KSUQ (SKL-U benchtop), with latest bios available (100.1)
Comment 1 Timo Aaltonen 2016-04-01 06:27:02 UTC 
disabling rc6 works around the issue

KBL GT2 works fine with the same stack, btw
