[Bug 1487484] [NEW] Installer crashing on system with Intel RST+mdadm

[Alex Wakizashi]

Public bug reported:

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.
