Two possible causes:
- UKIs don't work with mem attribute protocol + secure boot enabled, this is
likely due to systemd's borked hooking of the SEC ARCH 2 protocol pointer,
which i assume is in protected memory...
- grub page faults when running chainloader on kernel.efi , or linux + boot on
kernel.efi, the exact cause of this is unclear right now. but probably because
systemd-stub incorrectly marks itself as NX_COMPAT despite not being so.
Both of these things need to be investigated.
I think we should get rid of the mem attribute protocol in ubuntu's edk2
until these are fixed.
