Comment # 5 on bug 1033674 from Takashi Iwai

Are you using secure boot?  If so, try to disable it.  It makes the debugging
almost impossible.

So it's a CherryView.  It's working more or less stably, but the support status
of Cherrytrail platform isn't good with 4.4.x kernel, unfortunately.  It's
getting better with the recent upstream, at least, 4.12 will get more fixes.

I noticed some other kernel warnings / oops in the log, and this looks like
happening at hibernation resume.  Did you resume from S4?  The GPU hang might
be a side-effect of that, too.
