Have you compiled your kernel with CONFIG_FB_EFI=y? Can you hook up a
serial console and see if anything is emitted? Can you tell if your
machine has hung while trying to load the kernel image or is it just
that the kernel has boooted but isn't printing anything on the screen?

Hmm.. Keshav has also run into this problem with the old tianocore shell
and I haven't been able to get to the bottom of it yet.

Can you try the latest version at,

	https://github.com/mfleming/efilinux.git

And if that version still doesn't work can you apply the following patch
to efilinux and see if you are returned to the EFI shell after trying to
load the kernel, i.e. it should no longer hang, but it won't
successfully boot the kernel either.
