Title:
  Ubuntu freezes on boot when asking for encryption password on kernels
  newer then 3.19.0-28-generic

Status in linux package in Ubuntu:
  New

Bug description:
  I have my main partition encrypted. When I start my computer, Ubuntu
  will prompt me to enter my disk encryption password. This works fine
  on the kernel 3.19.0-28-generic, but if I use any of the newer
  kernels, like 29, 30, 31 and 32, the system appears to freeze as soon
  as it gets to the prompt screen.

  I can't actually tell whats going on when its frozen. The only symptom is that it does not accept keyboard input anymore, so I can't actually enter my encryption password. Nothing happens when I press the keys. It might have been that
  1) the whole computer had a kernel panic, 
  2) it might be frozen in some other way,
  3) or it may be just that something went wrong when setting up my keyboard to accept input and that the computer is otherwise running fine.

  I don't really know, all I can really tell is that if I go back to an
  older kernel, like 28, it works absolutely fine, but anything newer
  and I can't boot my computer at all.
