mt7921e kernel driver issues

[Matthias Beyer]

Hi,

I am seemingly experiencing the same issue on my (wifes) tuxedo OS
running with

    linux-firmware/noble-updates,noble-security,now 20240318.git3b128b60-0ubuntu2.19 amd64

on

    $ uname -a
    Linux [REDACTED] 6.14.0-115036-tuxedo #36~24.04.1tux1 SMP PREEMPT_DYNAMIC Mon Nov  3 17:34:07 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

The journal tells me:

Reboot wont help.
