I have this problem too on Lenovo Thinkpad X201 laptop with Intel Core i7 L-620 CPU. I use Debian jessie (testing) 64-bit with KDE. The problem appears when I try to use hardware video decoding via vaapi (I use vlc player) after some minutes of playback. I noticed the problem appears when I use "i915.i915_enable_rc6=1" in kernel cmdline. Because of this I can't use the power saving for Intel's GPU.

(In reply to Mihail Kasadjikov from comment #1) > I have this problem too ... Mihail, yours is not the same.
Chris, please have a look at this one.
It's just the old, old snb semaphores hang. Should be prevented here: http://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=requests
(In reply to Chris Wilson from comment #5) > It's just the old, old snb semaphores hang. > > Should be prevented here: > http://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=requests Do we have a bug for this on fdo so we could close this one?
Do we have a bug! https://bugs.freedesktop.org/show_bug.cgi?id=54226 is celebrating its second anniversary and is the most frequently hit hang in abrt.

Oh, *that* one. I'll close this one here, let's have all the glory in one place. (In reply to Chris Wilson from comment #5) > Should be prevented here: > http://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=requests Mihail, testing that is still appreciated; please report any results at either bug. Thanks.

Thanks. Sorry, I can't use kernel from this repo directly because I use Reiser4 and it is not ready for 3.17. I will try to extract only DRM/intel part but I'm not sure...
