[SOLVED] Can't load kernel modules after update from 5.11.15 to 5.12

Hi all,

I have always been using plain and simple Arch, always following the official instructions to install it. During the last installation, I created an install script, which is virtually just 1:1 transcription of commands on the wiki - I can share, should someone considered it useful.

The issue is that when I update the kernel version and reboot, I get

Failed to start Load Kernel Modules

The error is simple as that, nothing else appears.

By trial and error, I found out, that the latest kernel version that works for me is 5.11.15. I also figured out that I can exclude certain packages from update, so my current /etc/pacman.conf contains

IgnorePkg   = linux linux-api-headers linux-headers linux-firmware

I am 100% sure I am not pulling any other packages that could break something. The most recent occurrence was updating only the aforementioned ignored packages, when I wanted to just try out if anything has changed with the newer kernel.

To go back to working system, I have to downgrade the linux package from cache to the specified version. I can fully reproduce everything.

I noticed some people were facing problems with graphics when upgrading the kernel - I also encountered such issues and was able to tackle it by installing a different graphics driver, but then, the error above appeared.

I wonder if it could be that my HW triggers some obscure kernel bug or if I'm just doing something wrong - can't find myself what though...

You forget to mount the boot partition or boot the root partition.
Either way you end up booting an old kernel and that doesn't fit the updated modules.
Check "uname -a"
