## Observation

On the machine "aarch64" within the openqa.opensuse.org system, which is a
transactional system, the system failed to boot after a nightly system upgrade
on 2020-01-14. I could pinpoint that the upgrade of grub2-arm64-efi
2.02-lp151.21.6.1 -> 2.02-lp151.21.9.1 triggers
error: symbol `grub_efi_allocate_any_pages' not found.
when trying to load the kernel and initrd image after grub.

See
https://progress.opensuse.org/issues/62102
for details where I originally recorded the problem.


## Workaround

So far I did `zypper al grub2-arm64-efi`.
