That bug report is about issues (so far AR5416 only reported with the PS issue)
about disconnections with your AP if PS is left enabled by default which will
trigger dynamic PS to be enabled by by default, its all about 2.6.32. The fix
on 2.6.32 which should help AR5416 (so far concrete device with issues) is
to disable PS by default.

You can also disable PS manually if your kernel has it enabled:

iwconfig wlan0 power off

Your post on that bug report is very different, you say you have merged
wireless-testing into your kernel (why??), you also posted a log but
it doesn't contain the initailization part of ath9k so your card device
cannot be seen. What card is this with?

Please keep stable kernel bugs apart from wireless-testing bugs. Wireless-testing
is bleedinge edge and as such if you have issues you should use ath9k-devel or
the linux-wireless list (like this) and not post on bug reports for stable bugs.
