Akkana, I don't see any particular bad in that debug output. OTOH, since your kernel is not crashing anyway, there is not necessarily anything wrong with the drm kernel module in your case. Can you try "top" and see what's busy? I guess the Xorg server is stuck on something, in case it would be nice if you could get a trace or stack dump: https://wiki.ubuntu.com/DebuggingProgramCrash
My bug is maybe a different one, because my machine hangs for real (kernel freeze).
