With the 2.6.27-rc6 kernel I find that my wireless connection dies after a few
minutes. Using nm-applet I have to disable wireless and re-enable it before I
can re-establish a session (using WPA).
I tried pulling the wireless-testing branch and found it behaved strangely as
well - within about 30 seconds of idle time it would die. But, it would
usually immediately begin to reconnect (and succeed). My logs were full of
"ForceXPAon: 0" messages which I found were from ath9_hw_reset(), which were
all being called from set_channel, during the scan that took place when the
card was not associated with the AP. It typically occurred every 30-35 seconds.
I also found that if I kept a ping session to my wifi router running, then the
wireless connection would not die, it would operate normally.
It seems that it all worked fine in 2.6.27-rc4...
