I've tried disabling every combination of devices possible. The only
change that fixed the problem (surprise, surprise) was disabling the
integrated em NIC and or the nvidia card. I don't have another PCI
express video board to swap with unfortunatly; so, I can't test that

I should mention that disabling acpi also works, but it appears that SMP
won't work without acpi.

vmstat -i without apic:

Total                            2163442       1576

Oddly, the dmesg output is the same weither or not the apics are enabled
or not?
