[Bug 1458569] Re: System freezes randomly
I just had a freeze using rc8 BUT it happened when I was also using the
performance governor - that is, no CPU cycling going on.

** Description changed:
After 10 min or so, or an hour.
- Workaround seems to be locking the CPU freq to something. I'm guessing
- there might be a bug in the powernow-k8 driver that exhibits itself in
- systems with the XPRESS 200M GPU chipset.
