Comment 22 for bug 539609

My system hangs very often and seems to be related to hibernation or power down on no use. I leave the system and come back and it's hung. There are a few ways it hangs i.e. when overly busy but often when doing nothing for long periods.
A hang today with a Sysrq dump shows (I think) i915 as the pid farther with as the trace getting a 120 second timeout at __mutex_ock_slowpath.
I'm running Ubuntu 9.10 with all updates as of 4-12-2010. This happened on 10.04 LTS also.
I have a few traces with mem and blocked from sysrq if anyone would want to look at them.
