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.
