It fixed panic in my case too.

Unlike bwi(4) bwn(4) works much better with this card:

ssb0: <Broadcom BCM4311 802.11b/g Wireless> mem 0xf4000000-0xf4003fff
irq 17 at device 0.0 on pci16
ssb0: unsupportted coreid 0x817
bwn0 on ssb0
bwn0: WLAN (chipid 0x4311 rev 10) PHY (analog 4 type 2 rev 8) RADIO
(manuf 0x17f ver 0x2050 rev 2)
bwn0: DMA (32 bits)
bwn0: [FILTER]

and basic wep works just fine.

But I got panic in 'bwn taskq' if I play with hardware RF switch.
