--- Comment #8 from Daniel Vetter <daniel at ffwll.ch> ---
If you blacklist i915.ko and it still happens it's certainly not our bug, but
we still need to figure out what's wrong to unblock testing.

Bisecting should still be possible: As soon as you hit the backtrace you know
that a given kernel version is broken. To make sure a kernel is really good
just run the suspend/resume test in a loop for e.g. 100 repeats or so. Of
course you first need to make sure that you have a solid baseline.

It'll take some time, but if you script the suspend loop it shouldn't take more
work than a normal bisect.
