Help. Kernel errors, can't find common consensus

[Jim Popovitch]

Sorry for the chatter, but I am running out of places to look/ask...

What does this mean, wrt a stock+FL-updated RH7.3 server (no ACPID, APM, 
etc):

     kernel: Uhhuh. NMI received for unknown reason 31 on CPU 0.
     kernel: Dazed and confused, but trying to continue
     kernel: Do you have a strange power saving mode enabled?

It repeats abt every minute, over and over.

Clues?  Hints?  Possibilities?

Tia,
