Tony if you have time please try with the attached patch. Its
possibility of fixing your issue is very less. This patch does fixes a
kernel panic thing in another AR9285 card(fortunately the issue got
reproduced every time when i connect to an AP).
The difficult thing for me is to reproduce your issue. I can try
hard to reproduce your issue when I get some ample time.
Attached diff patch which you can try with your compat wireless with
the patch -p1 command.
thanks,
