And this is the important bit of information. You are having IRQ routing
problems. Evidently the smp kernel can not properly set up the apic IRQ
routing on your machine. Try going into the BIOS and looking for an
option to set the BIOS MPS table to either version 1.1 or 1.4 and try
switching it from whatever it is to the other and see if it works. If it
doesn't, then you'll just have to add noapic to your default kernel boot
line until someone knowledgable in ioapic issues can resolve your
machine's problem.
