Cc-ing Daniel (who is now an GRUB2 maintainer).
Is this by chance an EFI box?And you are booting using EFI GRUB2?

Hi everybody,
I'm amazed at and grateful for your interest in my issue. It is an efi
system and the grub2 version is:
% grub-install -V
grub-install (GRUB) 2.02~beta3
The menu entry is obtained by the following script in /etc/grub.d/
/etc/grub.d/43_custom_xen
It's attached (largely mutuated by the one I use to boot the Arch Kernel
without Xen)
I do apologize for the top quoting in the preceding mail: I was on my
mobile.
Greetings
