Which is where it probably belongs so I've moved it back.

Both ath and usb devices appear to be sharing irq 10; one is Giant locked and 
the other not.  It should work but it appears not.  If you can separate the 
irq's in the bios that might make things work.  Otherwise try booting with 
debug.mpsafenet=0 and see if the problem goes away.

FWIW I run several laptops with ath devices and usb mice (w/ and w/o sharing 
irq's) and have seen no issues.
