Johannes,

I tried to figure this out from the code, but I kept getting lost.

When a computer goes into hibernation, which of the mac80211 callback routines
are called, and which ones on the following resume? The problem arises due to
the problem in Bug #14267. The routine to check the hardware status of the
RFKILL switch is being entered with b43_status() returning 0, thus the hardware
switch is not checked. If we do not check for that condition, then we get a
machine fault on PPC. I would like to be able to track this problem down. I've
already entered two bad patches in this area.

Thanks,

Larry
