I've retrieved the ieee80211_node.c and if_run.c and recompiled wlan.ko and if_run.ko. Here results: Case 1: both if_run.ko and wlan_amrr.ko are loaded via loader.conf stable/8: panic rev217511: panic Case 2: wlan_amrr.ko loaded manually _after_ if_run.ko but before creation of the wlan interface stable/8: panic on rate control rev217511: no panic, but rate control doesn't work; tx rate is fixed on 1 Mbit/s Case 3: wlan_amrr.ko loaded _before_ if_run.ko stable/8: panic on rate control rev217511: no panic, rate control works as expected So rev217511 partially fixes the issue. -- Alexander Zagrebin
