Yeah, if anyone can somewhat reliably reproduce this
Ok, I see. So the beginning would be to reliably reproduce the the hang. I have encountered it in any possbile situasjon, both when watching videos on Youtube and right after booting the machine and doing absolutely nothing.
I'll try around a little bit and see if I can find something that triggers this hang.
Btw: which kernel is known to be the "last good one"?
(you need to disable rc6 on ilk to not hit another issue which seems much easier to hit)
Ilk? If this stands for "Ironlake": I'm on Sandybridge.
and bisect it, this would be _very_ much appreciated - we've pretty much tested all possible "disable stuff" and "revert random patch" we could thing of, and we can't reproduce these hangs no matter how hard we bang our heads against this.
Bisecting will be a pain without being able to reproduce the hang reliably.
Atm we're trying to come up with ways to dump more debug information, >but with no clue whatsoever what's going on that's slow-going.
Is there anything at the moment I can do to help you to get a grip on this problem? My machine is a Core i5-420M laptop with 4GB RAM (Asus U45-JC).
