I'll have a go later. The strange observation so far, is that if
I enable the parts of auich_intr() (auich.c 1.123) which are #ifdef
DIAGNOSTIC, I don't see the fifo underrun. (I just tried that as
a debug/diagnostic/lockdebug kernel doesn't show the symptom.)

npx0: io 0xf0-0xff irq 13
attimer0: io 0x40-0x5f irq 0
fdc0: io 0x3f0-0x3f5,0x3f7 irq 6 drq 2
lpt0: io 0x378-0x37f,0x778-0x77f irq 7

bge0: interrupting at ioapic0 pin 16 (irq 11)
uhci0: interrupting at ioapic0 pin 21 (irq 9)
uhci1: interrupting at ioapic0 pin 22 (irq 5)
uhci2: interrupting at ioapic0 pin 18 (irq 3)
uhci3: interrupting at ioapic0 pin 23 (irq 10)
ehci0: interrupting at ioapic0 pin 21 (irq 9)
ahc0: interrupting at ioapic0 pin 18 (irq 3)
auich0: interrupting at ioapic0 pin 23 (irq 10)
piixide0: primary channel interrupting at ioapic0 pin 14 (irq 14)
piixide1: using ioapic0 pin 20 (irq 5) for native-PCI interrupt

and it's a pentium 4 with hyperthreading.

Cheers,
