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"?
If it's the ilk one we only know that 3.6.x series seems to be solid, and something in 3.7-rc (probably before -rc1) broke stuff. So not too useful.
(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.
Hm, then it could very well be something different, so I think we need to track this one as a separate bug. Can you please file a new one on bugs.freedesktop.org against DRI -> DRM (Intel) and attach dmesg when booting with drm.debug=0xe (just so we know what's in your box) plus the i915_error_state from debugfs once the gpu is hung (if you can get at that file, reboot kills it).
Thanks, Daniel
