wireless ral with bridging crashes

Greetings,
*CC Me in not on the list*
I upgraded my sources yesterday because I was having trouble with WPA
and ral0. That problem is fixed now. However, now I am getting different
crashes and core dumps.
I wanted to run a wireless access point on freebsd and I got that
working by itself.
On my wired network I have openVPN which uses bridging.
Using three interfaces on a bridge
(net.link.ether.bridge.config=rl0,ral0,tap0) I am able to crash FreeBSD
6.1-PRERELEASE with an ifconfig command only.
I'm running the default GENERIC kernel.
To reproduce this crash, all i need is to type is "ifconfig ral0
mediaopt hostap"
I have vmcore and other useful info if requested.
Procedure:
1- load bridge and wlan_* to loader.conf
2- setup bridging between three interfaces in sysctl.conf
3- run ifconfig ral0 mediaopt hostap
4- note that i didnt try to run hostapd before running ifconfig
Settings that I think are useful to debug this:
in loader.conf I have
console="comconsole"
bridge_load="YES"
wlan_wep_load="YES"
wlan_tkip_load="YES"
wlan_ccmp_load="YES"
wlan_xauth_load="YES"
wlan_acl_load="YES"
in sysctl.conf I have:
net.inet.tcp.blackhole=2
net.inet.udp.blackhole=1
net.inet.ip.fw.verbose=1
net.inet.ip.fw.verbose_limit=5
net.inet.ip.forwarding=1
net.inet.ip.fastforwarding=1
# OpenVPN
net.link.ether.bridge.enable=1
net.link.ether.bridge.ipfw=1
# OpenVPN
# net.link.ether.bridge_cfg=rl0,tap0
# net.link.ether.bridge.config=rl0,tap0
# Wireless AP
# net.link.ether.bridge.config=ral0,rl0
# Wireless and OpenVPN
net.link.ether.bridge.config=rl0,ral0,tap0
in dmesg I have:
