Card is a 4318:
06:02.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g]
802.11g Wireless LAN Controller (rev 02)
Subsystem: AMBIT Microsystem Corp. TravelMate 2410
Flags: bus master, fast devsel, latency 64, IRQ 22
Memory at d0002000 (32-bit, non-prefetchable) [size=8K]
Kernel driver in use: b43-pci-bridge
This has been working fine, but I've recently been seeing oopses with .32-rc2
from mainline git repo:
~$ uname -a
Linux lizzie 2.6.32-rc2-lizzie-00134-g84d88d5 #2 Thu Oct 1 00:08:23 EDT 2009
i686 GNU/Linux
Here's one, when I tried to unload b43, after
the card had stopped working:
