OK, a little tedious, but I got there (as advised). 
Using the Release list at  'https://launchpad.net/ubuntu/vivid/+source/linux'  I can state that the problem started between 3.16.0-28.38 (3.16.0-28-generic) and 3.18.0-8.9 (3.18.0-8-generic).
In order to test the latest 3.16 ... I used the Release list at   'https://launchpad.net/ubuntu/utopic/+source/linux'  and I can state that release 3.16.0-44.59 (3.16.0-44-generic) was OK.

Regards

Title:
  systemd-boot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Just upgraded from 14.10 to 15.04 and now Ubuntu fails to start from powering up. I select 'ubuntu' on the grub loader screen and then get a blank screen. Computer just hangs. Have tried Ctrl+Alt+1 etc., and also leaving for several minutes but nothing happens.
  Once I power down manually and restart and try again I see a message:
  'ACPI PCC Probe failed, starting version 219' and PC boots OK.
