I would suggest updating the BIOS. AND/OR, changing the MP level from
1.4 to 1.1 in the BIOS. I'm running 3 Dual CPU (AMD's) systems here with
FC1, and no problems at all. Unless you don't have many devices
connected to your system (Video, Sound, USB, Firewire, etc) then just
disabling the APIC from the Grub line will help. But if you run heaps of
devices, then I suggest to update the BIOS. The APIC controller simply
expands you IRQ's (Most systems I've seen it adds four extra IRQ's, and
others as required). So that the IRQ sharing is at a minimum, as some
devices don't like the IRQ addresses to be shared with other devices.
