Title:
  [INTEL UBUNTU 18.04 BUG] Installation of Ubuntu 18.04 beta on IMSM
  RAID doesn't works

Status in debian-installer package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:

  1. Create IMSM RAID in BIOS
  2. Boot to Ubuntu 18.04 installation
  3. Activate RAID devices in step “Detect disks”.
  4. Go to “Partition disks”

  Expected results:
  RAID volume is visible in “Partition disks” section. It can also be partitioned to fit requirements of the installation.

  Actual results:
  RAID volume is not visible in “Partition disks” section.

  
  Additional observations: 
  After switching to another console and checking " cat /proc/mdstat ", only raid container is assembled (raid volume is not visible). 
  As workaround:
  mdadm –I /dev/containerName (like mdadm –I /dev/md127) makes RAID visible in installer.
