I believe in duck bugs, if the range of broken commits looks the same,
and the behaviour looks the same, probably the cause is the same, or at
least I once can be investigated on real hardware and probably once
fixed the other might be fixed as well.

I have not deep knowledge of uefi/efi internals so I'll need some
pointers to figure out exactly why it happens.

Hopefully I will carve some time next weekend to play the restricted
bisect game.
