I can confirm this bug for my setup under Kubuntu 9.10:
> lspci | grep Ath
02:02.0 Ethernet controller: Atheros Communications Inc. AR5212 802.11abg NIC (rev 01)
> lsmod | grep ath
ath5k 107008 0
> cat /proc/version
Linux version 2.6.28-11-generic (buildd@palmer) (gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4) ) #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009
My current workaround is to use wicd instead of network-manager (apt-get install wicd) which works flawlessly without any periodic delays/hangups. There is a button called "refresh" which leaves the decision of when to rescan up to you. No patching/compilation required.
