Bug#1051271: GRUB2 2.12~rc1-7 prevent machine to boot

[Miguel A. Vallejo]

Package: grub2
Version: 2.12~rc1-7
Severity: critical

This morning I noticed an apt upgrade in Debian unstable/Sid upgraded
grub-common, grub2-common, grub-efi-amd64 and grub-efi-amd64-bin. The
upgrade went normally and no errors were shown. Then I turned the
computer off and after a few hours I tried to turn it on, but it
didn't boot, it tried to boot but finally showed the bios screen.

After booting with a live USB and chroot into the hard drive, I
downgraded those four packages to version 2.06-3~deb11u5, and after
run install-grub, the computer booted normally.

Anyone can confirm problems with version 2.12~rc1-7 and UEFI machines?

Thanks in advance.
