With the knowledge that the hang is caused by snapshots, some googling has brought up some duplicates:
https://bugs.launchpad.net/lvm2/+bug/360237
https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/995645

It seems the issue was hanging around since 2009 or earlier.

In Trusty (or probably even earlier distros) it was possible to work
around by setting a sufficiently long rootdelay, and eventually all the
LVs in all VGs came online. But since Utopic, initrd gives up
altogether. No matter how long my rootdelay is, my 2nd VG never gets
activated after the snapshot came online in the 1st VG.

Bug description:
  Hi all,

  I open this report based on the linked conversation I had on the linux-lvm mailing list, and the Ask Ubuntu question I posted regarding this case.
  https://www.redhat.com/archives/linux-lvm/2014-November/msg00023.html
  https://www.redhat.com/archives/linux-lvm/2014-November/msg00024.html
  http://askubuntu.com/questions/542656/lvm-vg-is-not-activated-during-system-boot

  I have 2 VGs on my system, and for some reason, only one of them gets
  activated during the initrd boot sequence, which doesn't have my root
  LV, so my boot sequence halts with an initrd prompt.

  When I get to the initrd BusyBox prompt, I can see my LVs are inactive
  with "lvm lvscan" – then, "lvm vgchange -ay" brings them online. The
  boot sequence continues as I exit the BusyBox prompt. The expected
  behaviour would be that both VGs should activate automatically.

  On LVM mailing list, I've been advised it may be a problem with Ubuntu
  initrd scripts, hence I report this problem here. (I'm not sure if I'm
  reporting it to the correct place by assigning it to "linux", but I
  didn't find a package directly related to the initrd only, so I
  assumed initrd scripts are maintained by the kernel team. If you think
  it's an error, and know the correct package, please reassign!) Our
  suspicion is, initrd prematurely issues "vgchange -ay" before all the
  PVs come online. This makes sense.

  I already tried to set the "rootdelay" kernel parameter to make initrd
  wait longer for the boot LV to come up, but it didn't work. Note
  however, it worked with previous kernel versions.

  The problem came up when I upgraded to Utopic, and got kernel vmlinuz-3.16.0-23-generic. When I boot with the old kernel from Trusty (vmlinuz-3.13.0-37-generic), it works fine.
