I'm having the exact same issue and it is making my whole system quite 
frustrating to use. dmesg shows a lot of warnings in the form...

WARNING: at drivers/net/wireless/b43/

... followed by a stack trace, but that's the only clue that something 
is not quite right.

I'd prefer to be able to provide a bit more relevant information when 
opening a bug report, but if I can't get to the bottom of it soon I will 
just go ahead with it.

cheers,
