b43 doesn't reset hardware when loaded/unloaded [severity: minor]

b43 doesn't reset hardware when loaded/unloaded [severity: minor]

[Thomas Ilnseher]

Hi!

I upgraded my kernel to 2.6.24, and
so I also upgraded from bcm43xx to b43.

There used to be a problem with bcm43xx that after 
resuming from Supend-To-Ram, wireless didn't work anymore.

This however could be fixed with bcm43xx using the following 
sequence:

killall dhcpcd
killall wpa_supplicant
ifconfig wlan0 down #nb: the if was renamed from eth1 to wlan0 via udev
rmmod bcm43xx
modprobe bcm43xx
ifconfig wlan0 up
wpa_supplicant -iwlan0 -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf\
-B -P/var/run/wpa_supplicant.pid
dhcpcd wlan0

It doesn't work with b43. (of course replacing bcm43xx with b43).
I *assume* that the core isn't completely reseted on insmod'ing.

regards,
tom

PS: keep the good work!
also, tux-on-ice works, so this is just a minor annoyance.

This should be fixed in 2.6.24.1. A patch is available in the wireless-2.6
tree.

Fixed in wireless-2.6 and will be fixed in the upcoming 2.6.24.1.
