Ping on this problem, still seeing

Uhhuh. NMI received for unknown reason 3c on CPU 0.
Do you have a strange power saving mode enabled?
Dazed and confused, but trying to continue

on my Pentium-D system here with latest Linus head.

its sometimes 3c, sometimes 3d, I'm going to bisect and push for
reverts if nobody still has any clue about how to fix this.

Dave.
