FC2: SMP problems on IBM X330 server

[Richard Welty]

i have an IBM X330 which has run well with a single CPU and
FC2 for a while now. i recently acquired a second PIII for it and
am having no luck getting it to work with the SMP kernel.

the kernels i've been using are:

$ rpm -q kernel
kernel-2.6.6-1.435
$ rpm -q kernel-smp
kernel-smp-2.6.6-1.435

the CPUs are a pair of 1266MHz PIIIs, both of the same stepping,
and both pass the built in CPU diagnostics w/o trouble. with both
CPUs installed, the non-SMP kernels boot and run just fine.

when i try to bring the SMP kernel up, it starts but after it reports

using cfq io scheduler

it then starts having problems with the IDE CD-ROM driver (all
the hard drives are SCSI drives on a RAID controller):

ide0 at 0x1f0-01f7, 03f6 on irq 14
ide-cd: cmd 0x5a timed out
hda: lost interrupt

it spends some time retrying; i've not attempted to wait it out
to see what happens over time.

i've rooted around a bit with google and on the list archives
at marc.theaimsgroup.com without finding anything on this
issue. anyone have any suggestions what to do next?

thanks,
   richard
