Hello!
A while ago I had a situation where my AR9485 would lock up the kernel
so bad and two very nice guys(Mohammed Shafi and Adrian.. Uhm.. Sorry I
forgot his last name) were very patient in helping me and trying to
debug it through patches, etc. Nothing worked.
Eventually, though, I noticed that when I removed the atl1c module my
wlan started working. "Awesome!" I thought... Until I noticed this other
problem.
Once in a while, seemingly at random, the wlan dies with the error
messages in the title. And I can't possibly restore it without
restarting the computer.
With this message I have attached a log with the error messages.
This has been a problem since.. Uhm.. Kernel 3.2.something and I'm
currently running 3.2.8.
For some reason it happened at least 3-4 times shortly after each other
today - so I thought I might ask on here what's happening.
Hi!
Which kernel didn't this happen in?

Please try this patch with powersave enabled, using a recent
compat-wireless build (3.3 or linux-next based):

Hi,
I don't recall _how_ to do this, but would you mind verifying whether
you're actually somehow using power saving modes or not?
Thanks,
Adrian

I just tried it and will see what happens! That might take a while,
though, because it seems to occur at random.
But you know something? The thought has struck me before that it might
have something to do with power saving. Interesting :)

disabling power save would be a nice idea, to see if this issue disappears.
i got the same issue after a long stress test with some other card, sujith
gave me the idea to see if disabling PS helps
sudo iwconfig wlanX power off
sudo iw dev wlanX set power_save off
also please ensure that you run with your power adapter :) i noticed
PS gets enabled
via wext when we plug out the power adapter
