First some background: starting with Debian Wheezy I noticed my wireless
connection would fail after hours (sometime as quick as 15 minutes) of
uptime. Moving from Debian's 3.2 kernel to upstream's 3.9-RCs also
showed the problem.
Yesterday I pulled the linux-wireless git repo and built myself a kernel
(starting with Debian Wheezy's kernel config) with HEAD pointing to:
commit e514a9747148e3786879cc5430775a854441ba38
Author: Stanislaw Gruszka <sgruszka@redhat.com>
Date: Thu May 2 09:43:57 2013 +0200
ath5k: do not reschedule tx_complete_work on stop
After about 10 hours of uptime with the system basically idle (since I
was at work) I see the failure:

DMA engine when we start RX up
At this point the wireless connection is gone and can't be restored
without a full reboot.
In the past while looking at this with the upstream RC kernels I tried
setting ath9k.debug=0xffffffff, but it didn't seem to add anything
useful ( https://bugzilla.kernel.org/show_bug.cgi?id=56301 ).
Since the full kern.log is over 50 megs (lots of repeated error
messages) I'm only attaching the first 1000 lines which should be more
than enough.
Not sure where to go from here since I'm using the most current ath9k
that I could find. Is there anything else I could do to help get to the
bottom of this issue?

Step 0 - disable station mode power save; see if that has any impact.

The base station is an Apple Airport Extreme (version 7.6.3 in case that
matters). I don't see anything in the settings for power saving. And a
google search didn't help much.

No, I mean - there's an iw command to disable entering power save on
your linux station. Find that and disable it.

It has now been running for about 4 and half days without seeing the
wireless connection drop after the 'iw dev wlan0 set power_save off'. I
hope it's not premature to say thanks, as this is the longest I've seen
it go without a failure.
I'm not at all familiar with the history behind why power saving needs
to be disabled (as this machine is a desktop, it's not terribly
important to me), but if there's any hope of having it fixed through
patches, I'd be more than willing to help out so other people don't have
to go through what I went through.
Once again, thanks.

Hi!
please file a kernel.org bugzilla bug.
There's two overarching possibilities:
* there's a driver bug (eg setting up DMA when the chip is asleep);
trying to put the NIC to sleep during a DMA, etc;
* that some PCIe quirk needs to be added to the ath9k driver to work
around some oddities with PCie sleep state(s).
Thanks,
Adrian

I've updated the title and added the workaround to my previously opened
bugzilla ( https://bugzilla.kernel.org/show_bug.cgi?id=56301 ).
