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.

Bug description:
25.04 beta hybrid TPMFDE: first boot failure
Using virt-manager, creating a VM, adjusting the firmware for UEFI
(.ms), and adding a TPM (default settings), the resulting system
appears to install but fails on first boot.
The screen shows TianoCore along with
BdsDxe: loading Booot0003...
BdsDxe: starting Booot0003...
If I repeat this test with ubuntu 24.04.2 boot makes it boots as
expected, showing this prior to continuing to the desktop:
BdsDxe: loading Booot0003...
BdsDxe: starting Booot0003...
/EndEntire
/EndEntire
On 24.04.2, if I hit escape during the /EndEntire bit, I can see the
Grub menu offering the "Run Ubuntu Core" option, which never seems to
work on the 25.04 beta install.
