Are you saying that it used to work with that same kernel, or are you
saying that it worked with an older kernel?
It used to work with the same kernel. We had configured 5 identical laptops
in the office, including wifi. After some time this one laptop showed the
problem. AFAIU it crashed first, but I have no records about this.
My colleague turned off the laptop for a power off reset over night (if this
is possible for a laptop with a batter). Next morning Wifi was back. Seems
to be some reset issue.
In either case, do you have a working log?
This is what we get for the new (6.5.10, Debian backports) kernel now:

Hope this helps.
If you really have subdevice ID 0000 then something went wrong and you
have a blank OTP (now), which seems very strange.
This is an integrated NIC where part of the NIC is integrated into the
platform, and other parts are on the companion RF (CRF), so could also
be that the CRF module isn't seated well any more in the slot and it
just cannot access the data properly?
You mean there could be a problem with the wifi card not being plugged in
properly? We will check when my colleague is in the office.
