If like me you are using Fedora on your mac book, after the week-end and in case of reboot, your wifi should not work any more :(
Good, news, it's easy to fix, just add the following line to /etc/modprobe.d/broadcom-wl-blacklist.conf
blacklist bcma
Restart and enjoy wifi back ;-)
ps: of course you need to use:
kmod-wl-2.6.40-4.fc15.x86_64-5.60.48.36-2.fc15.6.x86_64
kmod-wl-5.60.48.36-2.fc15.6.x86_64
