Could you try running efilinux -m and see what you get? Though I suspect
that again, you'll be returned to the shell. Better yet, could you send
me the output of the "memmap" utility that comes with the shell and also
the output of "ver"?

I would guess the firwmare loader doesn't like the efilinux image and
it's not jumping to its entry point correctly. Can you successfully run
any of the sample applications from gnu-efi? Does grub2-efi run from
this shell?

Urgh, you're best bet at this point might be trying to find out which
function call hangs the system, e.g. by instrumenting efilinux with
"return EFI_SUCCESS;" and moving it forward in the execution path until
your machine hangs.

Wow, that was fast work, thanks for integrating efilinux :-)

Yes, these patches have already been sent to upstream gnu-efi.
