I've just had a similar problem with an IBM xSeries 232 - it would not
boot with apic enabled.. I chased the problem down to the network
adapter (fxp) - and when disabling the planar ethernet in BIOS it would
boot with SMP.
I managed to get both NIC and SMP working by disabling a bunch of stuff
in the BIOS, fx both serial ports and also the floppy drive.
Your problem might not be related, but give it a shot !
