Output of dmesg upon executing "modprobe iwlwifi"

After a distribution update yesterday, I was not able to bring the wifi interace up anymore. After some searching, I found out that the iwlwifi kernel module wouldn't load. I renamed the file it was trying to load `iwlwifi-so-a0-gf-a0-89.ucode.xz` to `iwlwifi-so-a0-gf-a0-89.ucode.xz.backup` (in `/usr/lib/firmware/`). The module then fell back to version so-a0-gf-a0-86 of the microcode, which loaded normally. 

After force-reinstalling the kernel-firmware-iwlwifi package (to check if the installation had somehow failed), the issue was back (as expected). This shows that the latest version of the package introduced the issue.

Problematic kernel-firmware-iwlwifi verion: 20240618-1.1
