[Solved] linux-zen 6.2.1 fails to boot via grub

Hi, not done much investigation of this yet as I need the computer in question for work so I've just downgraded the kernel for the timebeing. When trying to boot via grub using 6.2.1 I was getting "kernel does not support efi handover"

There's nothing super weird going on from a grub script perspective. A simplified version (which also doesn't work) is:

insmod part_gpt
insmod ext2
linux /boot/vmlinuz-linux-zen root=/dev/sda3  
initrd /boot/initramfs-linux-zen.img

Appreciate this isn't a lot to go on, just thought I'd do a quick post in case it was a common problem or anyone knew a quick fix.

Thanks!

Update your grub payload by running the appropriate grub-install command for updating GRUB with the latest package version 2.06.r456.g65bc45963 installed. If you are actually using a different GRUB than that could be the cause of the issue.

Re: [Solved] linux-zen 6.2.1 fails to boot via grub

You are using GRUB with unofficial patches (probably from some other distribution) that make it use the now deprecated EFI handover protocol. Arch's 6.2+ kernels are built without CONFIG_EFI_HANDOVER_PROTOCOL, so you will not be able to boot Arch's 6.2+ kernels using your current GRUB.

Follow https://wiki.archlinux.org/title/GRUB and install Arch's GRUB.

Edit: too slow.

That was indeed the problem. I had installed grub via a different distro on another partition and haven't touched either that distro or grub in a good few years at least No wonder if was broken.

All sorted now - thanks both!
