Current linus git bcm4xxx broken for me

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

I get that with current upstream git :

The error (with backtrace) is repeated every second or so. The card doesn't appear to associate.
It used to work with real old versions of the driver (though I never had it working above 11Mbits),
and I haven't tried again in the past few monthes mostly because I was too busy and couldn't be
bothered to try the new git based stuff.

Ben.
