No vmlinuz found with gentoo-kernel-bin-6.9.3 (arm64): "not recognized as any special format and unable to find version string in it"

Hi, can you help me understand what's going on here please? This is an ~arm64 system with sys-kernel/gentoo-kernel-bin-6.9.3:

I think new default gentoo kernel install procedure with Debian's 'installkernel' broke some things, installed kernels named "kernel-(version)-gentoo" by default now

I'm pretty sure this is caused by CONFIG_EFI_ZBOOT. It makes the kernel an EFI application.

By the way, this kernel is installed in the layout for systemd-boot, but your second comment seems to suggest that this is not the bootloader you are using. Is this correct?

Maybe you can give this patch a try and let us know if it helps: https://github.com/projg2/eclean-kernel/pull/53
