Created attachment 196419 [details] Full /var/log/messages from iwm panic. I tried to attach to an open of several open networks at "BornHack" yesterday and only managed to panic the iwm driver repeatedly. I belive the AP's were Ubiquity, and I can probably get hold of the people who runs them if need be. I have attached the full /var/log/messages as attachment, but here are what I guess is the top-level info: Aug 20 15:32:24 critter kernel: iwm0: rx ring: cur=96 Aug 20 15:32:24 critter kernel: iwm0: 802.11 state 3 Aug 20 15:32:24 critter kernel: iwm0: iwm_intr: controller panicked, iv_state = 3; restarting Aug 20 15:32:24 critter kernel: wlan0: ieee80211_new_state_locked: pending ASSOC -> AUTH transition lost Aug 20 15:32:25 critter kernel: iwm0: Failed to send binding (action:1): 35 Aug 20 15:32:25 critter kernel: iwm0: iwm_auth: binding update cmd Aug 20 15:32:25 critter kernel: iwm0: iwm_newstate: could not move to auth state: 35 Aug 20 15:32:26 critter kernel: iwm0: iwm_newstate: Failed to remove station: 35 Aug 20 15:32:27 critter kernel: iwm0: iwm_mvm_mac_ctxt_send_cmd: Failed to send MAC context (action:2): 35 Aug 20 15:32:27 critter kernel: iwm0: iwm_newstate: Failed to change mac context: 35 Aug 20 15:32:28 critter kernel: iwm0: Failed to send binding (action:3): 35 Aug 20 15:32:28 critter kernel: iwm0: iwm_newstate: Failed to remove channel ctx: 35 Aug 20 15:32:29 critter kernel: iwm0: iwm_newstate: failed to update power management Machine is Lenovo T480.
I'm experiencing the same issue. Running the same release of FreeBSD as OP. One difference in my case is that I get this error typically after resuming from sleep when connected to home network. Driver panics with iv_state = 2 rather than iv_state = 3 as in the original post. According to the messages my wireless device is: Intel(R) Dual Band Wireless AC 7265
Just wanted to update here. After upgrading to 12.1 the issue seems to have been resolved.
Seems to have been fixed along the way.
