Were you trying to play the video fullscreen?  If so, you'll need Jesse's kernel patches which make pageflipping work:

http://lists.freedesktop.org/archives/intel-gfx/2011-June/011014.html

Without those, most fullscreen apps will GPU hang.

I haven't tested video either way, though, so those may not fix the bug.

Note, that I'm pretty sure the MI_WAIT_FOR_EVENT code is only disabled on gen6. That will also cause a hang on gen7 with video and windowed swapbuffers.

Yes,Play the video fullscreen.
Test the commit 6a574b5b9b186e2 with above two patches, it fixed the problem (GPU hang and i915 state error)when play the video fullscreen(enable compiz).
But there is "Hangcheck" in dmesg.

I assume you mean the same behavior as bug#38362, hence marking dup.

I don't understand. Why doesn't it get gpu hang (as this bug)? because with Jesse's patches, or not full-screen?

This GPU hang exsits when play the video fullscreen on no-patches and no-compiz(Beacuse of bug 38362,disable compiz).
When test on Jesse's patches,it fixed GPU hang.
But video screen blank when playing video on firefox.It can reproduce by full screen switch(full-->not full-->full).
