Hi Baptiste,
It's been a while since I haven't tried iwlwifi, I tried it today on a vanilla:
15.0-CURRENT main-n276047-0849f1634a70 GENERIC-NODEBUG kernel.
When trying to create the wlan0 device: ifconfig create wlan0 wlandev iwlwifi0
You probably want to add regdomain ETSI country FR to not end up in the US.
it says:
The full dmesg since the load of the if_iwlwifi driver:
Thanks!

That's the first time we see one of those special ones.
Can you tell us what kind of Laptop this is?

Anything I am missing on my side?
No, likely not. Just the first one hitting this in all Intel internal code.
It's trying to see if it can read 6Ghz regulatory information from UEFI
(which LinuxKPI does not yet support) and so it should just fail but it
walks over it due to what looks like a wrong return code and tries to
program the unprovided information to firmware.
Can you bluntly give this a try and let us know if it helps?

Also, given 6Ghz is disabled by default in FreeBSD makes me wonder
if they are lacking a check. Seems all uncondiitonal. it's upstream
commit 4a9bb5b4d94999af8a9156e7004cad28db8cde38 so that I don't have to
look it up again in case we'll have to take it back to Intel.
Out of curiosity, does your AP support 6Ghz by any chance?
