This bug was fixed in the package lvm2 - 2.03.02-2ubuntu7 --------------- lvm2 (2.03.02-2ubuntu7) focal; urgency=medium
* Include raid1 in the list of modules installed by the initramfs hook, as this is not a kernel module dependency of dm-raid but if the user's root disk is configured as RAID1 it is definitely required.

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.
