this commit seems to fix it, what did you do to get this warning?
thanks! will revert this and see if it fixes this.
:) no, I meant the commit should have fixed your issue. i could not
understand, this commit should have been there before rc5 came.
also please post your lspci. thanks.
as for what I was doing, nothing just streaming radio, and cunducting
regular business, emails, twizzles, etc..
ok, thanks.

ath9k: Fix locking issue during tx completion
The received tx status of aggregated frame without BlockAck may
cause deaf state in AR5416 cards. So the driver does a reset to
recover. When this happens, we release the pcu_lock before doing
a reset as ath_rest acquires pcu_lock. This is ugly and also not
atomic. Fixing this addresses the TX DMA failure also.
ath_tx_complete_aggr can be called from different paths which
takes different variants of spin_lock. This patch also addresses
the following warning.

not sure whats causing this to fire off. i.g. at the motel6 I was
reliably seeing this occur. Now the last few days(not being at a motel)I
am not seeing this fire off. only thing that I can think of right now is
the friends house uses WPA instead of some open the browser and enter
the key code to access the internet(or maybe no WEP/WPA).
here is dmesg when being at my friends house, with no warning.
http://fpaste.org/2i7w/
I am going to be at a motel the next few days, so I will see if this is
reproduceable, and if I have time will bisect.
