Another confirmed instance of this on ath9k - on 2.6.31.2 and 2.6.31.3 - didn't
happen on 2.6.30.6 or 2.6.30.9. A couple other interesting facts:

- it seems to be related (at least in my case) to heavy transmit load -
I can download a kernel tarball without it failing, but if I try to
copy it to another system, it fails within 2 seconds reliably...
- running 'rmmod ath9k ath mac80211 cfg80211' followed by 'modprobe ath9k'
clears it up

No indication in dmesg except:

wlan<n>: no probe response from AP AA:BB:DD:EE:FF:GG - disassociating

and suddenly no packets going in either direction.

I'm in the process of moving back to 2.6.30.x for now...

I get this reliably by simple running a radio station
through mplayer(probably around 5/10 min of running)
when I run this commit:
2.6.31-rc8-00039-g03c3bbc I don't have this at all.
(I might of changed my .config without realizing it)

After running a bisect from this commit to current
I came up with nothing, which led me to believe that I must have through
the confusion changed something in my .config, or messed up
with choosing good/bad with the bisect because I didn't wait long enough for
this to fire off.

In any case either/or I'm still going to give a go at the bisect again
but this time wait longer(10/20 min) to really make sure I don't miss
anything.

BTW: when this hits for you is it pretty bad(no connection) i.g when this fires off over here
music still plays from mplayer, but did notice that mplayer player all of a sudden would die out, but
easily connected again.
