Give us your fstab and lsblk.

Or, the specific piece of information I want is where the kernels are located. When /boot is part of the root subvolume (not the default setup, sadly), then the kernels will be snapshpotted along with the rest of the filesystem. /boot/efi would be where the efi system partition is, and where the bootloader is installed.

If /boot is instead the efi parition (default setup lmao), then this means that when you restored a snapshot of your root subvolume, your kernels were not downgraded. I suspect that older kernels attempting to read/view newer kernel modules would cause this boot failure.

Please post more details

Also I don’t want to be that guy but for me personally I would stick to the beaten path. Stick with the mainstream stuff that is stable and well tested. CachyOS is Arch based and does not have anywhere near the stability of something like Linux Mint.

Start by following the instructions on the screen in order to get an error log.

I saw similar error when I had a drive mounting line in /etc/fstab

When i commented out the line it went back to normal.

Maybe try ctrl-alt-delete?

Put in your root pw and then look at the logs. You might need to mount disks to do so.

Have you resolved it yet? First thing would be finding out why did it kick you into emergency mode ie whats the actual error
