HP Proliant ML350 kernel panic

[Mark Hamilton]

I'm running RH9.0 with a 2.4.26 kernel on an HP Proliant ML350 server.
This is one of 3 identical machines, the other 2 servers are live
without any problems, so far.

The kernel panic is intermittent. This particular instance occurred at
boot time, but it will reoccur randomly while the machine is up and
under various load conditions. I've been unable to trigger the panic.
