  Mounting encrypted home and video driver fail at kernel update

Status in linux package in Ubuntu:

Bug description:
  Updated from linux-image-3.13.0-63-lowlatency to linux-image-3.13.0-65-lowlatency and at the following boot login failed and row-res mode appeared.
  I tried `update-initramfs -k -u` in recovery mode but it didn't help. It seems that the graphical login fails because of a failure to mount the encrypted home.
  On all the previous kernel updates, no such problem occurred.
  Booting into the older kernel works fine.
