ummmm ok....I will keep monitoring this system...I just swapped out
processors today...the powernow-k8 msg was doing it but then...the
system is running fine...seems like it anyway...I did not mean that the
whole sys "stopped" just that the powernow msgs stopped.

right now...I just wanna see it run 2-3 or so days w/out goin nuts like
the other proc did that I just replaced lol

thx
