Ah okay, got it, thanks. Very narrow window though :-) as the alloc_ordered_workqueue doesn't need RTNL and there is a long way to go to do if_add() from user and setup the driver for interrupts.
True, I do wonder how this is hit. Maybe something with no preempt and a uevent triggering things?
Again depends on the driver though, it should properly handle pending ieee80211_register_hw() with start().
It could, but it'd be really tricky. Much better to fix mac80211.
