Title:
  crypt passphrase prompt not visible when using splash boot option

Status in cryptsetup package in Ubuntu:
  Confirmed

Bug description:
  I performed a minimal x86_64 network install of Ubuntu 15.04 using the
  encrypted LVM option.

  When I boot the machine, I do not see a prompt to enter the decryption
  passphrase.  Instead I see the usual black screen with a message that
  systemd 219 is staring up and the boot process hangs.  When I type on
  the keyboard, the characters are echoed back onto the screen.

  I discovered that if I remove the "splash" option from the kernel boot
  command line in grub, the prompt to enter the passphrase does appear.
  So I have temporarily worked around this problem by removing "splash"
  from /etc/default/grub and running update-grub.
