With the current wireless-testing tree, unloading b43 produces the lockdep log

to learn. Any help on understanding this problem is appreciated.
A few questions:
Is there any reason for using the global workqueue and not mac80211's workqueue?
My original thought was that we needed the firmware load queue before mac80211
was running for b43; however, I now realize that my thinking was wrong.
Why is the workqueue cancelled in the core_stop callback? Wouldn't it make more
sense to cancel it in bcma_remove/ssb_remove?
It certainly would.
This would probably fix the circular dependency. But I'm not entirely sure,
because
I'm not that familiar with the code anymore.
I know that a lot has changed, but your instincts are still good.
Thanks,
Larry
