Don't know why. 2.6.29.1 works fine.

dmesg and config attached.

dmesg

I unloaded ath5k module later, because the NetworkManager seemed to scan through all available frequencies again and again. This scanning used a lot of cpu.

Thanks for the report.  I didn't see any association request -- I wonder if scan time is now exceeding network manager's built-in timeout.  Any chance you could bisect just the changes in drivers/net/wireless/ath5k between 2.6.29 and 2.6.30 to see what broke?

Other possible things to try: configure wpa_supplicant to only scan a subset of the available frequencies, or try this patch:

linked to patch fixes this bug for me!
Thanks. Will this patch go into linus' tree?

Comment 5 John W. Linville 2009-04-29 18:02:35 UTC

It is currently queued for 2.6.31...
