.. so the first LOR is between node table lock and comlock - the former in ieee80211_timeout_stations() and the latter in ieee80211_set_tim(). So, something is holding the comlock when the node table lock is being grabbed. Where is that happening? Would someone like to tackle that particular issue? Eg, what about printing out a witness backtrace if the comlock is held when the node table lock is held? And vice versa? Just to try and figure out who is holding things incorrectly?
