In order to add iwlwifi wlan0 device as a lagg port, one must add if_iwlwifi to kld_list in rc.conf. However, when doing this, the wlan0 device (an AX201 in my case) does not associate with an AP on initial boot. 'service netif restart' after initial boot will result in successful AP association and Wifi connectivity is generally reliable after that. Relevant rc.conf entries: kld_list="if_iwlwifi i915kms" ifconfig_re0="ether c4:75:ab:f3:f9:6c" wlans_iwlwifi0="wlan0" ifconfig_wlan0="WPA" cloned_interfaces="lagg0" ifconfig_lagg0="laggproto failover laggport re0 laggport wlan0 DHCP" Relevant dmesg output: wlan0: Ethernet address: c4:75:ab:f3:f9:6c lo0: link state changed to UP lagg0: IPv6 addresses on re0 have been removed before adding it as a member to prevent IPv6 address scope violation. lagg0: link state changed to DOWN lagg0: IPv6 addresses on wlan0 have been removed before adding it as a member to prevent IPv6 address scope violation. re0: link state changed to DOWN iwlwifi0: Microcode SW error detected.

Has anyone been able to take a look at this? I'm happy to do more testing if there's anything else I should try.
I upgraded to latest stable commit today (stable/13-n256387-7af7a0d1b14 AMD64 amd64) and re-tested. Everything is now working as expected. Thank you!
Can you please report back in a week or so if still everything is fine. From my side nothing has changed since the last reports (possibly not from you) came in, so I am suspicious as to what has changed to make it work now... [ please keep PR open ]
When I ran mergemaster yesterday, I happened to notice the following change: https://github.com/freebsd/freebsd-src/commit/052211e08c0e227277d0c4dc603bba2253eb3d73 Could this have been the problem, and removing the wpa_poststart function fixed it?
Also for this one. Any more firmware crashes? I am asking as I might merge the code from 15/14 to 13 as well and would love to have a "defined state" before that.
(In reply to Bjoern A. Zeeb from comment #5) This problem has not happened again. iwlwifi on 13-STABLE has been rock solid for me over the past month.
Thanks for reporting back. I'll close the issue then.
