[Bug 1756348] [NEW] [INTEL UBUNTU 18.04 BUG] Installation of Ubuntu 18.04 beta on IMSM RAID doesn't works

[Michał Żyłowski]

Public bug reported:

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.
