freebsd stable - Nov 2007 - [7.0-BETA2] Loading the wlan_xauth module by hand freezes the machine

Hello,

I have upgraded my gateway to 7.0-BETA2. It has a WiFi PCI card serving
some other machines:

Nov  9 19:55:59 passerelle kernel: ath0: <Atheros 5212> mem
0xfbed0000-0xfbedffff irq 18 at device 2.0 on pci2

At boot, the following message is displayed:

Nov  9 19:42:16 passerelle kernel: ieee80211_load_module: load the wlan_xauth
module by hand for now.

and then of course WPA is not enabled:

Nov  9 19:42:16 passerelle hostapd: ath0: DRIVER Error enabling WPA/802.1X!

Trying to `kldload wlan_xauth.ko' freezes the machine.

Fortunately, everything goes well if I load wlan_xauth in loader.conf!

Regards,
