RAID can be assembled using the imsm conatiner, BUT it does not get
resammbled automaticaly upon boot and is considered degraded and has to
be rebuild, thus is not usable right now.
There's support coming into debian for IMSM Raid on installer level, maybe useable in ubuntu too.

Bug description:
I use two 2TB Enterprise WD Disks on a Intel Server Board SK1200KP
with E3-1220L CPU.
I created a container array for IMSM metadata.
mdadm --create --verbose /dev/md/0 /dev/sd[c-d] --raid-devices 2 --metadata imsm
Then I created an array based on the imsm container.
mdadm --create /dev/md/1 /dev/md/0 --raid-devices 2 --level 1 -c 128 -z $((1836*1024*1024))
Then I tried to access /dev/md1 using parted and the kernel panic occured.
