The dump is Ok. b43 init: mutex_lock(wl->mutex) rfkill_init() mutex_lock(rfkill->mutex) in operation: rfkill poll (no locks held) calls into rfkill mutex_lock(rfkill->mutex) b43_rfkill_soft_toggle() mutex_lock(wl->mutex) As you can see the lock ordering of the two mutexes is different. The problem is that we cannot easily drop the wl->mutex on b43 init, as that would introduce some race conditions. This is specific to b43 and rt2x00 most likely doesn't have this requirement. I'm not sure how to properly fix this. -- Greetings Michael. - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
