Sometimes iwlwifi becomes unavailable on our Tuxedo laptops
running Debian's kernel 6.1.90, 6.1.94 or 6.1.99. The error message
in system log is

We have to turn off the laptop for a few minutes to make it work
again. A reboot is not sufficient.
The path into this failure is still unknown, but an unclean shutdown
might be relevant here.

We have upgraded the firmware to the most recent version 20240709 from kernel.org
(linux-firmware-upstream_20240709_all.deb, built using upstream's python script).
No improvement.
Installing 6.7.12 or 6.9.7 from the bookworm-backports repository seems to help.
We haven't had a single incident using these kernels on the Tuxedos.
