Could be. (might not be a driver problem.)

I've got

lock order reversal:
 1st 0xffffff8000a257d0 run0_node_lock (run0_node_lock) @
/usr/src/sys/net80211/ieee80211_ioctl.c:1326
 2nd 0xffffff8000a24018 run0_com_lock (run0_com_lock) @
/usr/src/sys/net80211/ieee80211_node.c:2486
 (line numbers are of old 9-CUREENT but referring the same lock)

Also, I've got

lock order reversal:

Here are suspicious part (Though, I don't have any solutions.)
