GRUB version 2.02~beta2-9ubuntu1.2

Booting a grub image w/ the progress module on a certain arm64/EFI
systems causes GRUB to crash w/ Synchronous Exceptions. This isn't
reproducible in QEMU.

Reproduction. The simple case is to create a grub image with *just* the
progress module:

$ grub-mkimage -v -o grubaa64.efi -O arm64-efi -d
/home/dannf/x/usr/lib/grub/arm64-efi progress

Booting the resulting image:

[1] PXE
[2] ubuntu
[3] Shell
[4] Boot Manager
Start: 1
..

Synchronous Exception at 0x0000000FF7C3DDC8
