I just ran into this. My first load of master-2010-08-05 was fine but
I started getting a lot of disconnects on AR9003 hardware after a
period of RX'ing data over an encrypted legacy network. Instead of
checking dmesg I just rebooted though. After that I connected to the
same AP again, started Rx'ing for a while and then shortly got this:

After a reboot I got a hard hang which I could not capture any logs
for. I rebooted and am up now but not seeing these issues yet. John,
does this smell like what you were seeing or is this different?
