Title:
  Cannot enter cryptfs password on boot

Status in Linux Mint:
  Confirmed
Status in plymouth package in Ubuntu:
  New

Bug description:
      Version and Edition: 
  Linux Mint 18 beta (x64; Cinnamon Edition)

      Problem and reproduction and what happened: 
  When running plymouth (i.e. kernel boot options "quiet splash"), with a seperate /boot partition (~512MB;ext4) and encrypted root (~64GB; ext4 created in installer using Physical Volume for Encryption), the graphical password prompt appears but accepts no input. This is after a dist-upgrade on 2016-06-09 ca. 0200-0400 UCT, with intel-microcode and nvidia-361 custom hardware drivers.

  The password text is echoed on terminal 7 (Alt-F7), but does not
  attempt to unlock the volume. A reboot (Ctrl-Alt-Del) at this point
  seems to corrupt the partition, which I can boot into using recovery
  mode, force fsck, resume boot about 50% of the time. Otherwise, a few
  repeats and I'll be back into the system. (fsck on /,
  /dev/mapper/sda6_crypt, ext4 does find orphaned inodes, etc)

      Expected:
  Password would be accepted in plymouth graphical screen (i.e. echoing dots for password) and system would boot normally after unlocking root partition (/).

      Frequency:
  This seems to happen on every boot/reboot, as long as "quiet splash" is in the kernel options. Editing /etc/default/grub and removing the kernel lines shows a text-based password prompt, which unlocks the volume flawlessly. Data corruption still seems to occur on reboot, though.

  Changing resolution to 1920x1080 (native panel resolution) does not
  seem to affect the graphical screen. Only removing the "quiet splash"
  yields consistent behaviour.

      Hardware:
  Dell Latitude E6520 (ca. late-2010), 16 GiB RAM, 240 GiB OCZ Vertex3 SSD, Intel i7-2720QM CPU, nVidia NVS 4200M.
