I do ten times suspend/resume cycles with a latest kernel, 5 times resume is
ok, another 5 times cause call trace and system hang..
I also try to bisect this, but as you know, this issue is not so stable, so I
can't find the first bad commit..

By the way, this issue happens no matter whether i915.ko loaded or not, i.e. if
remove i915.ko, sometimes it happens, sometimes it doesn't, so maybe this is
not our bug?
