    I am/was inclined to remove that tag, but the problem is likely caused by firmware which is too old for the 'backported' patches that upstream applied.

    The driver fills the eventlog with millions !!! of messages, see below.
    It otherwise works. The problem can be reproduced on different NUC systems.

    If you downgrade the kernel version, does the issue then go away?

    https://unix.stackexchange.com/a/721474 looks related and the solution is to upgrade the firmware to a newer version.
    That isn't available on Stable, but grabbing ``firmware-iwlwifi`` from Testing should be safe. Not sure if that version is new enough though.

    https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/
    is the upstream repo and you could 'grab' the firmware files which `dmesg` reports it can't find.

    My guess is that those 'backported' patches expect newer firmware then that. -----BEGIN PGP SIGNATURE-----
