>Description:
	
I have an amd64 system running 9.99.92 from Halloween (about a week ago)
with an urtwn0 USB wifi interface:

[     2.301939] urtwn0 at uhub1 port 7
[     2.301939] urtwn0: Realtek (0x7392) 802.11n WLAN Adapter (0x7811), rev 2.00/2.00, addr 1
[     3.851931] urtwn0: MAC/BB RTL8188CUS, RF 6052 1T1R, address 80:1f:02:d3:ad:65
[     3.851931] urtwn0: 1 rx pipe, 2 tx pipes

I've installed pkgsrc/wip/aircrack-ng. Running "airodump-ng urtwn0"
causes a panic:

 nic: kernel diagnostic assertion "mutex_owned(&sc->sc_write_mtx)" failed: file "/usr/current/src/sys/dev/usb/if_urtwn.c", line 4423
