Description W 2024-01-13 13:52:13 UTC 
I want to boot up alpine linux from openSUSE Tumbleweed aarch64 grub.efi but failed.

Files are:
https://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/EFI/BOOT/grub.efi
https://dl-cdn.alpinelinux.org/alpine/v3.19/releases/aarch64/netboot/vmlinuz-virt
https://dl-cdn.alpinelinux.org/alpine/v3.19/releases/aarch64/netboot/initramfs-virt

```
menuentry "alpine" {
    search --no-floppy --file --set=root /vmlinuz-virt
    linux /vmlinuz-virt alpine_repo=http://dl-cdn.alpinelinux.org/alpine/v3.19/main modloop=http://dl-cdn.alpinelinux.org/alpine/v3.19/releases/aarch64/netboot/modloop-virt
    initrd /initramfs-virt
}
```

grub shows:
```
error: ../../grub-core/loader/arm64/efi/linux.c:61:invalid magic number.
error: ../../grub-core/loader/arm64/efi/linux.c:302:you need to load the kernel
first.

Press any key to continue...
```

Reference:
The magic number header field check on aarch64 has remove on grub 2.12.
I think openSUSE should follow up.

Hello,

The patch removing the magic number check has been submitted to openSUSE:Factory and will be released in a few days.

https://build.opensuse.org/request/show/1142178

It has also been verified by the alpine kernel and initrd link in the Description.

Set the resolution to fixed, feel free to reopen if it doesn't work after updating to the released package.
