ath5k v0.5.0 on 901go with AR2425 no reconnect after wakeup

Kernel: 2.6.27-13-eeepc from array.org with corresponding modules.
Log: ath5k phy0: Atheros AR2425 chip found (MAC: 0xe2, PHY: 0x70)

After suspend and wake up on 901go knetworkmanager cannot reconnect to my wlan access point. While I never had this problem with kernel 2.6.27-11-eeepc this problem is now reproducible with 2.6.27-13-eeepc.

Currently, the only work-around is to first unload the modules ath_pci, ath_rate_sample, ath_hal, ath5k, and then to modprobe ath5k again. Afterwards, connecting to the wlan acess point becomes possible again.
