Title:
  Cannot boot full disk encrypted system, impossible to type password

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After last kernel upgrade (3.19.0-30-generic) I'm no longer able to
  start the system.

  1. Press power button.
  2. System shows

  Ignoring BGRT invalid status 0 (expected 1)
  ACPI PCC Probe failed
  Starting version 219

  (AFAIK this text is the same when everything works)

  3. System ask for full disk encryption password.

  4. Cannot type password (see attached video).

  
  * Selecting previous kernel (3.19.0-28-generic) in grub allows me to boot normally.
  * In a different machine I can use last kernel with full disk encryption without problems.
