Public bug reported:
Following advice as per Release Notes
(https://wiki.ubuntu.com/VividVervet/ReleaseNotes)
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.
This has repeated each time from scratch.
FYI
lsb_release -rd
