Unfortunately, the above lines do not give enough info. Which firmware gets loaded depends on about a dozen variables because Intel likes to make even the most simple things complicated. I am looking for a line from dmesg which looks like this. iwx0: using firmware iwx-QuZ-a0-hr-b0-77 > with kernels prior December 1 and with the > > most recent kernels. Both worked perfectly before PMF commits. Can you perhaps pin-point this issue to a specific commit? Was it if_iwx.c,v 1.194 / git 1b86c9c3d6e54f79b1038372b3b3f310d63993e9 or was it a different change? > MacOS/iOS have no problems with this AP.

Please send a pcap file which contains beacons from the AP: tcpdump -n -i iwx0 -y IEEE802_11_RADIO -s 4096 -w /tmp/iwx0.pcap Put the interface down, start tcpdump, put the interface up, wait until a transition from SCAN to AUTH or RUN is shown in dmesg debug output, then stop tcpdump and the file should contain what we need.
