[TriLUG] Strange lockups on Fedora

[Nathan Yinger via TriLUG]

Got home from work and it was locked up again. Oddly, the mouse cursor
still moved, nothing else updated on the screen. The clock showed 13:24, so
it had been frozen for a few hours. After killing Xorg, the mouse cursor no
longer moved.

Looking in top, I saw that the largest CPU user was one of Firefox's 'Web
Content' processes, which was very consistently using 5% CPU. Maybe
something in the new Firefox?

I wasn't sure how to reload the amdgpu module, since it was in use by 36
other modules.

Tonight/tomorrow I will try leaving it on without Firefox running.
