lockup during boot with SMP kernel

[rchart@xxxxxxxxxxxxxxxx]

Hi,
I wonder if anyone can give me some
pointers to resolving a problem I'm having when trying to run FC1 with
an SMP kernel.

I have an Intel SR1300 1U standard server
with dual Xeon 2.8GHz, Adaptec 2120S SCSI controller setup for hardware
RAID. It should be great configuration, but I'm hitting persistent problems
with the server locking up during boot. It doesn't always happen at the
same place - sometimes during new hardware check, or when bringing up the
interfaces, or when it has got as far as the login prompt. 

I was originally running 2.4.22-1.2115
kernel. I just applied kernel-2.4.22-1.2174.nptl.i686.rpm and kernel-smp-2.4.22-1.2174.nptl.i686.rpm
- but the new SMP kernel does the same thing. All is fine with a single
proc kernel.

Anybody seen this elsewhere or have
a suggested resolution path?

Thanks!
