On my i7 2620M (Lenovo T420) the gpu frequently hangs when decoding videos (vaapi) and running OpenGL apps/games at the same time. Disabling iommu makes my system relatively stable even with rc6 enabled. I haven't played with the semaphores however. Can you please try my ppgtt branch from my fdo repo at http://cgit.freedesktop.org/~danvet/drm/ ? Note thought that it'll only work on snb/ivb and that suspend/resume is broken. Also, it won't properly re-enable ppgtt when resetting the gpu after a hang. But testing feedback highly appreciated.
