You must include all the modules you need in your signed image (i.e. on
the grub-mkimage command line). GRUB has no provision for verifying
module signatures, so loading modules would amount to reading and
executing unsigned code in the same security context as a signed image,
which is not a sensible thing to do.
You can find the list of modules we include in our pre-signed images in
the grub2 source package, specifically debian/build-efi-images.

[Quantal] forbids to loading mormal.mod in UEFI security boot
Status in “grub2” package in Ubuntu:
Invalid
Bug description:
I follow the step in https://wiki.ubuntu.com/UEFI/SecureBoot to do security boot test on my machine.
I have signed grubx64.efi and put it on /boot/efi/efi/ubuntu/grubx64.efi, I also add test-cert.der to KEK and DB.
Then I enable security boot and boot to shell, Once I run grubx64.efi, the system report following error:
error: Secure Boot forbids loading module from (hd0,gpt2)/boot/grub/x86_64-efi/normal.mod.
how can I resolve it ?
