Subject: Disassociating atheros wlan with 2.6.31

Greetings,

When moving from vanilla 2.6.30->2.6.31 I noticed that I get dissasociated from
my wlan hub with regular intervalls. This did not happen on 2.6.30.
I cant see any pattern aside from that it happens at regular intervalls
(around 10-15mins). It works again when I re-identifies myself.

Got an Asus 1000HE with Atheros chipset.
Havent had time to bisect it, just wanted to check
if this is an known issue. Ive ruled out faulty wlan hub
since everything works fine when going back to 2.6.30.

nothing much on dmesg:
