The problem is that on upgrade, Ubuntu picks a driver that hangs common commands like sudo, ifconfig etc. and prevents any networking.
There are no questions on upgrade, and Ubuntu picks this driver even if brcmsmac was used previously.
Most users that are subject to this bug won't be able to recover their installations.
I am subject to the bug every six months.
