Bug Description
Observed Behavior:
During the install of Yakkety or Xenial on a ppc64el VM system with an encrypted LVM setup, post-install fails to boot successfully. A black screen is shown after the grub prompt. The user does not even get to enter their encryption key.
Expected Behavior:
I should received a prompt to enter my encryption key and the system should boot up successfully.
Steps to Reproduce:
1. Obtain a Xenial [1][3] or Yakkety [2] server ppc64el ISO
2. Start install, select "Guided - Use entire disk and set up encrypted LVM" otherwise choose defaults.
3. Post-install the system will start to boot and you will get a black screen. Text is printed in clear text, changing to other consoles does not help or provide any additional details.
4. If you reset and boot into recovery mode, which will ask for your encryption key and then boot into recovery mode successfully. Once there, you can continue to boot the system will boot up successfully as well.

[edit 1] - added original 16.04 ISO as also failing and clarified this is on a VM system, not baremetal.
