There again, it could possibly be an APIC problem. (That's not a typo:
there are two, vaguely related, Intel standards; one named ACPI and the
other APIC).

Try doing a
grep -i apic /var/log/dmesg
and if it comes up with 
ENABLING IO-APIC IRQs
somewhere, see what putting "noapic" on the kernel command line does.

Remember to keep an "emergency" unmodified entry in grub.conf!

HTH,

James.
