[Bug 1447978] Re: After update from 14.10 to 15.04 boot stops at black screen displaying "Starting version 219"

[i1abnrk]

I've had a very similar experience with the upgrade to 15.04. I've just
completed nearly 24hours of troubleshooting.  I got around my NVIDIA
problems here after a fresh install of 14.10 and some advice I found
here that helped. http://ubuntuforums.org/showthread.php?t=2263316 see
also my additional steps at comment #7

Title:
  After update from 14.10 to 15.04 boot stops at black screen displaying
  "Starting version 219"

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  I have just updated to Ubuntu 15.04 and keep getting "starting version
  219" error. The only way that I can boot in to Ubuntu 15.04 is to hold
  down the Shift key during start up and then boot in to Safe mode.

  Without doing anything else, if I then select "Resume normal boot"
  Ubuntu 15.04 boots up okay.
