I think this is the first time we have seen a device that uses b43legacy with
any radio kill hardware. I suspect that the b43legacy_is_hw_radio_enabled() is
not looking at the correct bit. The hardware will obey the value on PIN13, no
matter what the driver does. That is why changing ...enabled() did no good.
Please build with the attached patch, and run 2 times, once with PIN13 connected
and once with PIN13 disconnected. That should let us see where the state of that
pin shows up.

Are these related to large packets? If you reduce the size to 1000, does it
still err?
