(Downstream bug report can be found here: https://bugs.archlinux.org/task/76062)

I run an ArchLinux system with unmodified GRUB package from their official repository.

Since package version 2:2.06.r261.g2f4430cc0-1 (GRUB commit 2f4430cc0a44fd8c8aa7aee5c51887667ad3d6c3) I noticed that I cannot boot with freshly installed GRUB anymore, because it enters rescue mode right after the encrypted /boot key slot gets unlocked:


error: symbol `grub_debug_malloc' not found.
Unknown command `normal'.
error: symbol `grub_debug_malloc' not found.
Entering rescue mode...
grub rescue> _


The original 2.06 release (commit ae94b97be2b81b625d6af6654d3ed79078b50ff6, package 2:2.06-5) works as expected.

Grub is installed with:


# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=ArchLinux
# grub-mkconfig -o /boot/grub/grub.cfg


For some reason the ArchLinux package is compiled with the '--enable-mm-debug' option. If I compile any version without that option I can successfully boot again.

Is this maybe just a downstream issue from them using the '--enable-mm-debug' option, or should this not happen at all?

Steps to reproduce:

  1. install grub > 2.06
  2. Generate grub config
  3. Reboot
  4. Unlock /boot slot


System info:

  • Linux Distribution: ArchLinux
  • Hardware: HP 350 G1 laptop
  • Grub version: Git master > 2.06 tag
  • Booting in UEFI mode & using cryptodisk feature with LUKS-encrypted /boot
