netcfg 2.8.2-1 cpu hangs

Hi guys,

I'm trying to get a laptop to connect to my WPA2-Personal network using netcfg.  I am able to connect manually, using:

wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
dhcpcd wlan0

Contents of wpa_supplicant.conf
--------------------------------------------------------------------------------------
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
update_config=1

network={
             ssid="2WIRE407"
             psk="password"
             proto=RSN
             key_mgmt=WPA-PSK
             pairwise=CCMP TKIP
             group=CCMP TKIP
             auth_alg=OPEN
             }
--------------------------------------------------------------------------------------
I copied the "wpa" netcfg profile to "/etc/network.d/homewpa".

Contents of homewpa
--------------------------------------------------------------------------------------
CONNECTION='wireless'
DESCRIPTION='A simple WPA encrypted wireless connection"
INTERFACE='wlan0'
SECURITY='wpa'
ESSID='2WIRE407'
KEY='password'
IP='dhcp'

-------------------------------------------------------------------------------------

Output from "NETCFG_DEBUG="yes" netcfg homewpa

Any ideas?

Re: netcfg 2.8.2-1 cpu hangs

Update:

"ifconfig wlan0 down" always hangs... must be a driver issue (ath5k).
