Bug#1056764: grub-efi-amd64: can't boot with GRUB 2.12~rc1-12

[debian at mifritscher.de]

Good day,

does grub 2.12 (without rc1) help? There are a good pile of fixups
between rc1 and release. E.g.
https://git.savannah.gnu.org/cgit/grub.git/commit/?h=grub-2.12&id=1f5b180742ff2706bc3a696d115ddbc677ec75b9
or
https://git.savannah.gnu.org/cgit/grub.git/commit/?h=grub-2.12&id=67ae3981dc5113e5af3a0539174bcd7eab8f7722
could help.

Additionally, the ZFS fixes are needed to boot from volumes touched by
ZFS 2.2 ( https://github.com/openzfs/zfs/issues/13873 ), so migrating to
2.12 is helpful in either case.

Best regards,
Michael Fritscher
