Title:
  Ubuntu 12.04 fails to boot on PowerEdge R720/R720XD when running in
  UEFI mode

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  After installing vanilla Ubuntu 12.04 on a couple of PowerEdge R720
  and R720XD systems over the network, the freshly-installed system
  crashes the EFI BIOS instead of booting to the operating system.  A
  quick Google search yields that it appears to be an issue with how
  Grub is allocating memory, and a patch for the issue has been posted
  at http://savannah.gnu.org/bugs/?36532

  Switching go using legacy BIOS works, but is not an option due to its
  limitations on usable space on the RAID volumes the OS is installed
  on.
