Most recent kernel where this bug did not occur: 2.6.20
Distribution: Gentoo

Hardware Environment:
broadcom 4306 rev02
x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+

Software Environment: 
Gentoo Base System release 1.12.9
gcc-4.1.2, glibc-2.5-r4

Problem Description:
kernel 2.6.20 and earlier with gentoo patchset + ndiswrapper and
kernel 2.6.20 with gentoo patchset + bcm43xx driver:
 wirelesscard worked perfectly

kernel 2.6.21, 2.6.22 with gentoo-patchset + bcm43xx driver:
 poor connection, 10kbit downstream, several seconds ping time when loading
many things at once through the connection
 notice: in the testings I noticed, that rebooting is the only way (ok I didn't
try to wait several hours) to revise the problem. so when I start firefox, with
many pages loading at once, it doesn't help to stop the loading, close the
tabs, close firefox or even restart the init-service. only after a reboot
everything works again.

kernel 2.6.23_rc2 (plain vanilla) with bcm43xx driver:
 device doesn't work at all

With patches from ftp://lwfinger.dynalias.org/patches which creates a bcm4301
driver, that should work with my card according to
http://lists.berlios.de/pipermail/bcm43xx-dev/2007-July/005095.html :
kernel 2.6.22 with gentoo-patchset + bcm4301 driver:
 kernelpanic on boot

kernel 2.6.23_rc2 (plain vanilla) with bcm4301 driver:
 System hangs when trying to get up the interface (through init-script)
