Weird PCI interrupt delivery problem

[Craig Boston]

Sam, I hope you're reading -hackers, it seems errno.com is rejecting my
mail again...

Forward and reverse DNS looks OK, and I always send from the address
published in my SPF records; not sure why it doesn't like me.

Haven't been too worried about it yet, just counting my blessings that
the "Built-in 802.11g" turned out to be a working Atheros card.  Here's
the info:

ath_hal: 0.9.14.9 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413)
ath0: <Atheros 5212> mem 0xd0200000-0xd020ffff irq 11 at device 4.0 on pci9
ath0: Ethernet address: 00:11:f5:89:75:d4
ath0: mac 7.8 phy 4.5 radio 5.6
