[Phillip Susi]

Looks like this is an Intel fakeraid and that they don't seem to be
working right since the dmraid -> mdadm transition.

Bug description:
  My system is UEFI.  I am installing Ubuntu 16.04 desktop on btrfs on
  top of mdadm raid1.  Installer failed when trying to install grub-efi-
  amd64-bin.

  I expected the installer to complete or fail to install grub2.  I
  didn't expect it to crash.
