Bug description:
  [Impact] GRUB fails to load Linux on UEFI machines with certain firmware behaviour related to getting the memory map.  The known case is Dell PowerEdge 12G systems.
  [Test Case] Try to boot on one of these systems and make sure it's possible.
  [Regression Potential] It's easy to verify that the change is confined to UEFI.  It would definitely be worth regression-testing on other UEFI systems to make sure they can still load Linux too, though, as this is a fairly substantial change to the loader.

  Original report follows:

  We (Dell) would like grub2 patched in Quantal so that it is able to
  boot using grub2 on Dell PowerEdge 12G systems that are in UEFI mode.

  In May, we reported this bug in Precise's version of grub2 (although
  our patch has not yet been included in an update of grub2 for
  Precise). See <https://bugs.launchpad.net/oem-priority/+bug/1001009>.
  We provided a patch that works against grub2_1.99-21ubuntu3 as well as
  one that applies against version 2.00. I've included the one for 1.99.
  It has not yet been included in the grub2 package for Quantal.
