"Error loading kernel image" with hardware based disk encryption

Hello everyone,

for some reason, possibly a new version of systemd my system two days ago refused to boot. The error message on the screen looked like this:

../systemd/src/boot/linux.c:125@linux_exec: Error loading kernel image: Unsupported 
../systemd/src/boot/boot.c:2640@image_start: Failed to execute Arch Linux (6.14.3-zen1-1-zen) (\EFI\Linux\arch-linux-zen.efi): Unsupported

My first guess was that for some reason mkinitcpio -P had not been triggered after the update of the nvidia dkms driver, but it turned out that it also had something to do with a missing update to the bootloader.

I'm not entirely sure which of the following steps fixed it, but as a cooking receipt it might come in handy regardless. So if you encounter a similar error here's what to do (replace "nvme0n1p1/2" with whatever your partitions name is):

1. Go into BIOS and switch off secure boot

2. Boot from Arch USB stick.

3. $ cryptsetup open /dev/nvme0n1p2 root

4. $ mount /dev/mapper/root /mnt

5. $ mount /dev/nvme0n1p1 /mnt/boot

6. $ arch-chroot /mnt

7. $ mkinitcpio -P

8. $ sbctl sign-all

9. $ bootctl update

After that exit the chroot environment, umount the filesystems and reboot. Don't forget to turn on secure boot again. Everything might be fine now.

Good luck

Dirk
