Bug Description
I recently upgraded to the hwe-16.04 kernel and X server.
I am unable to boot the 4.10 series hwe kernels. At the plymouth splash screen I just see the message, "cryptsetup: lvm is not available" over and over again, and I am never asked for my FDE password to unlock the luks-encrypted root partition. I've observed this in both 4.10.0-33 and 4.10.0-35 kernels.
This never happened with the 4.4 series kernels. In fact, I can still choose a 4.4 series kernel in the grub menu, boot that, and it works fine -- no error message, asks me for my password, mounts root, and off we go.
The error "lvm is not available" is particularly strange in that it shouldn't be needed -- this system has no lvm containers. I only use device-mapper.

We ran across another instance of this bug today, on a different system.
A production back-end (no GUI) server had been mistakenly configured to pull packages from xenial-proposed, and it updated to kernel 4.4.0-119 this morning. It then failed to boot with the exact same symptoms described above. It boots just fine when manually selecting the 4.4.0-118 kernel.
Now we're down to one release increment...
4.4.0-118: bug is absent, affected systems boot just fine
4.4.0-119: bug is present, affected systems fail to boot
