Title:
  boot in xenial shows black screen instead of plymouth logo /
  encryption prompt

Status in plymouth package in Ubuntu:
  Confirmed

Bug description:
  After updating to xenial, I see nothing but a black screen after EFI
  boot successfully.  I can blindly type my disk encryption password to
  get the system to evenutally boot to a GDM prompt, but there's no
  visual feedback before that point.  At first I thought it was because
  the initrd wasn't created properly on upgrade from wily
  (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1546342), but
  forcing it to regenerate by apt-get install --reinstalling the kernel
  didn't fix it.
