Kernel images fail to boot with Failed to execute / UEFI Load Error

I have been using Secure Boot with Unified Kernel Image and systemd-boot for a couple of years using the instructions from
https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot
https://wiki.archlinux.org/title/Unified_kernel_image

This worked fine until a month ago or so with Garuda updates that no longer build a functional kernel. I receive the errors mentioned in the title when trying to run linux-zen-signed.efi, even with Secure Boot disabled. It fails early on, so the kernel doesn’t start at all, we don’t get to initrd or any of that, and the machine simply boots the next available OS or returns to firmware setup instead after showing the error.

This happened on two separate computers when rebooted after garuda-update, at different times this September, and with one having Intel and the other AMD hardware. I’ve tried looking up the error messages online to no avail, nobody else on the Internet seems to have this problem.

A kernel image that doesn’t load: https://zi.fi/linux-zen-signed.efi

The problem is beyond my skills (with objdump or other tooling), but if anyone wants to have a look at why this kernel doesn’t load up and to which part of the build might be causing issues here, I would highly appreciate it.

And while this problem is looming, I won’t be doing any garuda-update on my laptop that still boots up fine with the same Secure Boot setup. I can also get a kernel image from it for comparison if that is of any use.

Welcome to the forum
Can you provide your

garuda-inxi

as per the forum template

Cool, but if you read the post you’ll notice my two desktop machines don’t boot at all, so I cannot run that. Both have ASUS gaming motherboards, one is a Ryzen5 and the other a modern Intel build.

Hey vas, I haven’t used secure boot before so just giving some general advice based on what’s been happening on forum for a while.

  1. Make sure that your device’s SATA controller is set to AHCI mode in your UEFI. Quite a few issues propped up on forum lately where people couldn’t boot anymore and this was the issue so kindly just ensure you have this ruled out.

  2. Try to chroot from a live usb and try to use a different kernel such as mainline or lts kernel to rule out the possibility of this being a zen kernel bug. Quite a few people have been having issues with zen kernel lately.
    2.1 You can chroot from live usb using the command garuda-chroot -a which will automatically detect your disk to chroot into or if this fails (happens in ventoy)
    2.2 you can go the manual route following this guide :point_right: How to chroot Garuda Linux. Please note this guide goes on to reinstall grub which you don’t need to do you can just use the pacman commands to download a new kernel (plus whatever other steps are required to ensure that secure boot works with the said kernel).

PS: you can provide the garuda-inxi from live iso as well it will help us know if there are any other issues identifiable.

I have rebuilt the unified efi file by using objcopy to extract sections linux, initrd and cmdline of the broken one and then rebuild with systemd-ukify.

objcopy linux-zen-signed.efi -O binary -j .linux linux
objcopy linux-zen-signed.efi -O binary -j .initrd initrd
objcopy linux-zen-signed.efi -O binary -j .cmdline cmdline
/usr/lib/systemd/ukify build --linux=linux --initrd=initrd --cmdline=cmdline

The produced linux.unsigned.efi boots fine. Still need to figure out what is wrong with pacman hooks that make the build. Also I didn’t sbsign the manually constructed image yet.

My systems didn’t have systemd-ukify installed, and installing it didn’t remove anything else. Something else builds the (broken) UEFI unified kernel image, from Pacman hooks, whenever the kernel is upgraded. Can anyone help me squaring out which package and/or scripts are responsible for that?

What are you using to generate the initramfs? It looks like you have both dracut and mkinitcpio being detected here:

Please reinstall your kernel and paste the input/output into the thread so we can take a look.

It would seem that mkinitcpio is being used for that. Unified kernel assembly appears to be a separate step after initrd and kernel images are already created separately (prior to part 5/5 below where unified image is made), so it should no longer concern mkinitcpio I think.

The gap warnings I have seen before but not “section below image base”. Perhaps that is the problem? By log it seems that objcopy is being used directly but this still doesn’t say by which script, also not which EFI stub (ukify uses systemd-stub).

Thanks for your guidance.

Grepping all of /usr for the message shown yielded results… The image update is done via this hook that calls sbupdate to do the work.

rw-r--r-- 573 root 26 Sep  2021  /usr/share/libalpm/hooks/95-sbupdate.hook
.rwxr-xr-x 6.4k root 26 Sep  2021  /usr/bin/sbupdate

I suspect this is installed via yay from AUR because I also found ~/.cache/yay/sbupdate-git/. Github of sbupdate is archived, with final commits - in August 2023 - making it use systemd-ukify…

Looks like I need to remove these outdated files and instead setup a hook to use ukify directly.

Since you are using mkinitcpio, did you set up the /etc/mkinitcpio.d/linux.preset file? Unified kernel image - ArchWiki

What Pacman hooks are in use? If you are using kernel-install to automatically install kernels in the UKI format you need to mask the direct kernel installation Pacman hooks. Unified kernel image - ArchWiki

mkinitcpio ships with a kernel-install plugin that generates the appropriate image (a UKI image for layout=uki). Other programs, such as sbctl, also ship with a kernel-install plugin.

To setup kernel-install to produce UKIs:

  • Set the kernel-install layout to ‘uki’. e.g.:
# echo "layout=uki" >> /etc/kernel/install.conf
  • Mask the direct kernel installation Pacman hooks:
# ln -s /dev/null /etc/pacman.d/hooks/60-mkinitcpio-remove.hook 
# ln -s /dev/null /etc/pacman.d/hooks/90-mkinitcpio-install.hook
  • Create a Pacman hook for kernel-install. You can use pacman-hook-kernel-installAUR.
  • Remove and reinstall the kernel packages that you use.

I’m not sure if that is the only way to do this, but if you are using mkinitcpio and systemd-boot I guess I would probably make sure that is set up correctly.

Problem solved. Got rid of sbupdate, sbkeys, mkinitcpio and some other outdated cruft. Ukify is also not needed because Dracut has this as built-in functionality. What I am using is:

  • systemd-boot (bootctl install)
  • dracut to build UEFI unified signed kernel directly
  • sbctl for Secure Boot key management (create-keys, enroll-keys)
  • pacman -S garuda-bootctl-dracut to install the above and have hooks for kernel upgrade etc.

Check with sbctl verify after installation that everything is signed. I needed to sbctl sign systemd-boot manually but kernels get auto-signed on pacman updates.

Thanks for the help in triaging this! I also found this post helpful: Reddit - Dive into anything
