I am experiencing a bug which causes my Atheros wireless driver
to error out and drop my connection, requiring a reboot to re-connect.

I am surprised that I haven't heard more complaints about this issue
which has plagued my hardware since ubuntu's later stable releases of
kernel 2.6.28 and continuing into linux=3.0.0-14-generic with ubuntu 11.04.

This is triggering at random times, usually once or twice a day, seems
to be slightly more likely during heavy network use

This is not happening as a result of suspend/resume.

It is not fixed by installing compat-wireless, neither by adding
"options ath9k nohwcrypt=1" to /etc/modprobe.d/ath9k.conf, nor by
setting power management options with iwconfig

There are several bugs on launchpad which describe similar problems,
such as this one:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/622265
but I would welcome suggestions of other bugs that may be more pertinent.

[I am connecting to a wireless G, wpa2 network.  Specific hardware is
03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless

Errors in dmesg generally look something like,
