It happens, because my test driver b43 handles all RX and TX-status callbacks in process context. I guess some part of the networking stack expects RX to be in tasklet and/or softirq context. We also have a report of this warning in wl1251, so it's probably not a b43 problem. -- Greetings, Michael.
