What motherboard are you using?  There are lots of us throwing out our 
Tyan S2466 based systems as fast as we can.  After a while they start 
exhibiting the behavior you're seeing (hard locks (no OOPS available)) at 
random times that are very hard to diagnose/resolve.

See the beowulf list archives for a fair bit of discussion of this.

All my machines with hang problems are using Gigabyte 7DPXDW-C.

FC 3 and Kernel Lock or Hang

[Tom Browder]

I have just noticed something about the FC 3 722 kernel that exhibits a
little different behavior after a lockup:

When I push my power switch to turn of the box for a hard restart (screen is
blank, no apparent reaction from a key press or mouse movement or click), I
get a momentary look at a good desktop as the display comes back before the
shutdown sequence starts.  I am not using any kernel boot arguments (except
'ro root=LABEL=/')

I hope this rings a bell with someone.

You say you push the power button, and the shutdown sequence starts?
Does it complete - i.e. does the computer shut down nicely?

Hmm... Sounds like an X hangup... Can you ssh in? if so, does X run at
99,9% CPU (check with top)?

Yes, nicely.

The graphics lock on my box on the kvm shows nothing unusual I can tell.  No
surging X.  Maybe I can get some more intel today.  And I'm interested in
testing new X11 if the experts think it feasible with FC 3.
