[ath9k-devel] Problem with ath9k_htc driver - freezes

[Dylan]

I'm having some trouble with the ath9k_htc driver freezing. I first 
noticed these using some compat-wireless stable drivers before kernel 
3.8 was released for my distribution (I don't recall exactly which but I 
THINK it may have been 3.8-rc7, though it likely existed earlier as 
well). It also occurs with the new 3.8 kernel itself. I am using 
Fedora's kernel. I'm currently running Fedora 18 and using kernel 
version 3.7.9-205, which works just fine - the issues start at 3.8.

The device I'm using is a TL-WN822N. It appears to be V3, which is odd 
as I'm pretty sure that only V1 and V2 use the ath9k_htc driver but I 
digress.

The freezes occur multiple times daily and there doesn't seem to be any 
recovering from them. I've had the occasional DE freeze before and been 
able to go to a new terminal, this isn't like that - all I can do to fix 
it is a hard reset. I also got some kernel panics when I was using the 
compat drivers but I can't confirm that was the ath9k_htc driver 
specifically and in any case they didn't seem to correlate with the 
crashes. I am pretty sure the ath9k_htc driver itself is the culprit 
since the crashes only occur while I'm using my TL-WN822N adapter, not 
my internal one (which does have its own problems).

I found references to similar issues happening in the past but mostly 
from 2010 and then apparently it was fixed. I just thought I should let 
someone know. I should be able to post any other necessary information 
from the actual crashes if you can tell me what you can use, it doesn't 
take too long for one to occur.
