That is known. I posted it once or twice. It is b43 making bad
assumptions about mac80211 behavior. And mac80211 behavior changed...
b43 does modify the number of queues in the data structure after it
registered things to mac80211. That used to work properly in the past.
But it breaks now. The init does have to be re-ordered and implementation
of async firmware loading is required to fix that.

It only works by accident anyway. But I already said that several times.
