I've got a bunch of SMP boxes running FC3 and FC4T3. Not all SMP boxes 
are created equal.

I've got a pair of Intel quad P3 Xeon boxes... they work fine, no 
special stuff needed.

I've got 4 dual P3-1000 machines (Gigabyte motherboards) These things 
suck. Unless you append acpi=off to the kernel boot string, they 
randomly reboot, hang, freeze, etc.

And a Compaq DL380, won't run single or dual cpu correctly unless 
acpi=off is appended to the boot options.

Try turning off acpi, that seems to fix lots of smp issues for me.
