Hi folks, i'm using a compact flash module, based on broadcom bcm4318
chipset, together with b43 driver from kernel mainline, and i get 'some'
troubles trying to associate with APs; here follows 'uname' and
'dmesg' logs:
>uname -a

Note that same stuff happens also with kernel 2.6.37, and same with old
firmware version 410.2160 (2007-05-26 15:32:10) cutted from
http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
while other firmware (version 478.104 (2008-07-01 00:50:23)) was from
http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2
Any help will be very very very appreciated
tks
