[Bug 107928] Screen regularly turns black, reboot needed

https://bugs.freedesktop.org/show_bug.cgi?id=107928

--- Comment #7 from Matthew Vaughn nethershaw@gmail.com --- I am able to reproduce this bug report in every detail on my machine. The only difference is that I am never present to directly observe the driver deadlock; it always occurs when I have left the machine idle for at least a few hours.

Both tests dwagner proposed yielded negative results.

I am attaching dmesg logs from the most recent instance of the problem.

Please advise. I run Gentoo, and am able to easily introduce patches into any part of the system for testing.
