hostapd "deauthenticated due to local deauth request"

[Ivan Voras]

I'm trying to setup an AP with a run0 interface on latest 8-STABLE but
apparently 802.11 association fails:

Oct 31 16:21:30 ursaminor hostapd: wlan0: STA 00:22:69:07:30:9e IEEE
802.11: associated

802.11: deauthenticated due to local deauth request

Oct 31 16:21:38 ursaminor hostapd: wlan0: STA 00:22:69:07:30:9e IEEE
802.11: deassociated

etc. Apparently the client never comes to the phase to receive DHCP address.

The client in this case is WinXP and the setup did work with 7-STABLE,
though with a bug in the rum driver which caused regular kernel panics
on the AP.

The devices are configured like this:

rum0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290
	ether 00:1c:f0:9d:08:b3
	media: IEEE 802.11 Wireless Ethernet autoselect mode 11g <hostap>
	status: running
wlan0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST>

hostapd.conf contains:

interface=wlan0
debug=3
ctrl_interface=/var/run/hostapd
ctrl_interface_group=wheel
ssid=Cosmos
wpa=1
wpa_passphrase=something
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP

Any ideas?
