 I've managed to come up with another flavor of hang.  I beat on it
 pretty hard this evening and although the system itself didn't hang, the
 interface did.  The interface and _just_ the interface became
 unresponsive.  After letting it sit for some time (it was dinnertime), I
 did an "ifconfig ath0 down" to see if I could get it to recover and it
 appeared to go into a loop, scanning through the channels trying to
 find an access point while the rate module kept trying to change the
 speed (although always to 6M, which seemed a little odd).
 
 I've put this console log on my website at
     http://www.exit.com/Archives/FreeBSD/PR-Info/ath-hang-console.txt
 
 That's the ath debug output of the whole session, so it's quite large
 (some 37K+ lines), but the most interesting bit is at the end.
