    _______________________________________________________

Details:

The statement in grub-core/lib/relocator.c:591:
  grub_mm_base = NULL;
causes my system to lock-up when booting in EFI mode. I have determined this
through liberal placement of grub_dprintf's, and eventually commenting out the
offending line.

By commenting this line out, I am able to progress further in the boot
sequence, but I am still unable to boot (have yet to determine *that* cause)

I haven't quite worked out why it only happens on EFI booting, since as far as
I can tell, it's not in an EFI-specific code section.

Also reported on launchpad as LP #1080521
