You might also try my 3.14 branch: http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.14
Not sure if there are any important changes in this branch, but so far it looks more stable for me. I haven't seen hangs while video was played, though the week before i got them almost daily. And have seen hand during start up only once for last week.
I might be just very lucky this week.
Still don't see hangs, but noticed but FPS is very low on this branch. Half Life is like a slideshow, though works fine with vanilla kernel.
