Bug#908852: Debian Stretch can't be installed or booted on Apollo Lake systems.

[Carlos Alberto Lopez Perez]

Package: grub-efi-amd64
Version: 2.02~beta3-5
Severity: important
Tags: d-i patch


There is a bug in the version of Grub2 shipped in Debian stable that renders
grub unable to boot in Apollo Lake systems (this are usually recent netbooks
or ultrabooks with Celeron/Atom CPUs).

The issue is that the EFI binary generated by Grub2 from Stretch hangs this
systems completely.

See: https://medium.com/@pawitp/grub-2-issue-on-intel-n4200-97c12d4db8af

The fix is simply to backport this patch https://git.savannah.gnu.org/cgit/grub.git/commit/?id=446794de8da4329ea532cbee4ca877bcafd0e534
(which applies cleanly over the grub version in Stretch).


I think it will be a good idea to release a new version of Grub2 for stable
with this patch and generate a new image of the debian installer.

Otherwise it is impossible (well, not impossible, but very difficult) to
install Debian Stretch on this systems.


Note that Debian testing is not affected, as this patch is already included
there. The fix is only necessary for Stretch.


I attach a debdiff of a backport I did myself. I have verified that Debian
Stretch boots fine on my Yepo 737A laptop (Apollo Lake) with this new version
of Grub2.
