  Kernel fails to update EFI vars, rendering system unbootable [P8P67
  PRO REV 3.1, BIOS 1904 08/15/2011]

Status in “linux” source package in Saucy:
  Fix Released

Bug description:
  After an upgrade, my system failed to boot.  Fortunately I was able to
  run the EFI shell and manually launch grub.  From there I discovered
  that the EFI boot catalog contained no entry for GRUB.  It appears
  there has been a regression in kernels later than 3.8.0-7 that causes
  it to fail to update the EFI variables.  After running grub-install,
  it reports no errors, yet fails to show the efi boot catalog as it
  does when it works.  Manually running efivars shows the ubuntu entry
  has been removed.  Checking dmesg shows:

  [   25.965586] efivars: set_variable() failed: status=8000000000000009
  [   25.981816] efivars: set_variable() failed: status=8000000000000009

  This happens on kernels 3.8.0-{15,19,23} but works correctly in -{6,7}.
