My system was built yesterday. I just figured I'm not using the entire
frequency range available in Europe. This is a potential problem when
AP frequencies are not under my control.

FreeBSD mobileKamikaze.norad 9.2-PRERELEASE FreeBSD 9.2-PRERELEASE #0 r254418: Fri Aug 16 22:15:55 CEST 2013     root@mobileKamikaze.norad:/usr/obj/HP6510b-91/amd64/usr/src/sys/HP6510b-91  amd64

Setting the country works.
# ifconfig wlan0 country de

But it blows up when trying to bring up the interface:
# ifconfig wlan0 up

kernel messages:
wpi0: need multicast update callback
kernel: wpi0: fatal firmware error

The wireless LED stays dark.

To reactivate the wireless interface I have to call
# ifconfig wlan0 destroy
# service netif restart wpi0

I can bring the interface up again without problems.
