Comment 21 for bug 192720

The way I got around this problem was: boot from CD and select Rescue Broken System; open a shell in the root system; use "vi" to edit /etc/modprobe.d/blacklist; blacklist bcm43xx and b43 legacy, as follows:

# replaced by b43 and ssb.
blacklist bcm43xx
blacklist b43legacy

The system then boots. To make wireless work I then followed these instructions: http://linuxwireless.org/en/users/Drivers/b43, specifically "You are using the b43-legacy driver". Of course, I didn't compile b43-fwcutter, but used the one from the repositories. The directory to put the firmware is "/lib/firmware/2.6.24-16-generic".

Now, to use the wireless I just type "sudo modprobe b43legacy", and it works (odd). If I don't "sudo modprobe -r b43legacy" before shutting down, the system hangs and does not power down.
