Title:
  Installer crashing on system with Intel RST+mdadm

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Installer started with "nodmraid" (if it's decided to migrate to mdadm, why dmraid still in installer ISO, and no mdadm here?)
  2 Intel RST RAID volumes - 2xSSD (/dev/md/FAST) and 2xHDD (/dev/md/SLOW) - for use with LVM caching later.
  Volumes partitioned with GPT.
  mdadm installed, partitions created, LVM volumes created. 
  Installer started, selected /boot partition and appropriated LVM.

  Installer crashed, seems like on grub-install.

  grub-install from live CD working perfectly.
