Ariff fixed a panic in uaudio a while ago after I've seen a panic  
(mail regarding msdosfs panic from me to current a while back). The  
fix is in rev 1.20 of uaudio.c  (Jan 26). I did test this and there  
was no panic anymore after playing a song.

Please make sure there's not stale version of uaudio.c in your tree.

I didn't try with a more recent -current myself, so the problem was  
either introduced between Jan 26 and now, or there's another problem  
around (I use uhci/ehci, not ohci).

Bye,
Alexander.
