Kirk's dmesg showed some interesting IRQ routing issues that might be
the problem:
pir0: <PCI Interrupt Routing Table: 4 Entries> on motherboard
$PIR: BIOS IRQ 11 for 0.7.INTA is not valid for link 0x22
$PIR: BIOS IRQ 11 for 0.7.INTB is not valid for link 0x22
Can you send me the output of http://people.freebsd.org/~msmith/pir.c
to make sure that's not the problem.
What does vmstat show for irq 10? How about other IRQs?
