I have the same problem. I'm using:
02:04.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
Subsystem: Hewlett-Packard Company Broadcom 802.11b/g WLAN
Flags: bus master, fast devsel, latency 64, IRQ 21
Memory at d0000000 (32-bit, non-prefetchable) [size=8K]
Kernel driver in use: b43-pci-bridge
with b43 driver and I can easily trigger similar Oops with:
# ip link set wlan0 up
# iwlist scan
The bug is introduced by commit 06d961a8e210035bff7e82f466107f9ab4a8fd94
("mac80211/minstrel: use the new rate control API").
The v3.9 is ok and the v3.11-rc1 is still bad. I haven't checked
wireless tree yet.
