[Carl Englund <1458569@xxxxxxxxxxxxxxxxxx>]

Have been trying vmlinuz-4.1.0-040100rc5-generic for about a week, using
the laptop for maybe 2h a day, mostly just running Facebook. I was
starting to hope but it froze again today. I was hammering ctrl+alt+f2
in hope of a console just after that, and to my surprise it switched
(but not immediately) to a black screen. Could have been a coincidence,
it might have done that even if I hadn't pressed anything. But after
that it was completely unresponsive.

Title:
   System freezes randomly

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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 CPU chipset.
