Bug description:
  After upgrading to Wily, raid1 LVs don't activate during the initrd
  phase. Since the root LV is also RAID1-mirrored, the system doesn't
  boot.

  I get the following message each time LVM tries to activate a raid1 LV:
  md: personality for level 1 is not loaded!

  Everything was fine with Vivid. I had to downgrade to Vivid kernel
  (3.19.0-30) to get my system to a usable state. I pretty much hope it
  to be a temporary workaround and I'll get the new 4.2.0 kernel work
  with Wily in days.
