wpa_supplicant and ath9k

[Clem Taylor]

I'm trying to bring up a system with the ath9k driver. After going
from 2.6.27-rc6 to wireless-testing, I managed to get WEP to
work (not using wpa_supplicant). Now, I'm trying to get WPA2-AES to
work and not having much luck. wpa_supplicant finds the AP, and
attempts to join the network but times out during authentication. I
was previously using a madwifi based card with wpa_supplicant 0.6.3. I
tried the ath9k with both 0.6.3 and 0.6.4. The AP is a Ubiquiti
NanoStation5 running v3.2.3734 configured for WPA2-AES and running
hostapd v0.6.3.

Any ideas what might be wrong?

                           Thanks,
                           Clem
