Subject: bug report: iwlwifi crash on ROG STRIX X670E-E GAMING WIFI

I've observed this bug on the following Linux versions:

linux-6.10.7
linux-6.11.2
linux-6.12.3
linux-6.13
linux-6.13.2

I don't have reliable steps to reproduce unfortunately, but I can tell 
you that it happens about every 1-2 days.

When it happens the system becomes unusable, some CPUs seem locked in a 
busywait in the kernel, and depending on CPU roulette, I have to hold 
the power button down for 10 seconds in order to reboot.

dmesg output follows:
