>Description:
I'm having issues getting my ath (AR5B91) wireless card working with a recent stable.  It was working with
8.0-RELEASE

I created wlan0 manually for debug
ifconfig wlan0 create wlandev ath0 wlanmode station country GB
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
ifconfig wlan0 10.0.0.1/25

if I then ping a known reachable IP on that network I cause a device
timeout.
[root at ostracod ~/wlandebug]# ping 10.0.0.32
PING 10.0.0.32 (10.0.0.32): 56 data bytes

Some device info
Its a Zotac ION-ITX-D Atom motherboard with an "Azurewave AR5B91"
wireless card.

I did try wpa instead of wep with the same results.

I've tried
wlandebug -i wlan0 debug+assoc+auth+output+power
and I get

>How-To-Repeat:
ifconfig wlan0 create wlandev ath0 wlanmode station country GB
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
ifconfig wlan0 10.0.0.1/25

if I then ping a known reachable IP on that network I cause a device
timeout.
