Title:
  update-initramfs fails for MODULES=dep when root is on LVM wich uses
  nvme device

Status in initramfs-tools package in Ubuntu:
  Fix Released
Status in initramfs-tools source package in Trusty:
  Fix Committed

Bug description:
  [impact]

  On a trusty system, if using MODULES=dep with lvm-on-nvme then update-
  initramfs fails to rebuild the initramfs.  This prevents using
  MODULES=dep for building an initramfs on trusty, with a rootfs that
  uses lvm on nvme.

  [test case]

  install a system where the rootfs uses a LVM logical volume that is
  located on a physical volume on a NVMe drive.  Edit the /etc
  /initramfs-tools/initramfs.conf file and change the MODULES line to
  MODULES=dep and save the file.  Then run sudo update-initramfs -u
  which will fail with:

  $ sudo update-initramfs -u
  update-initramfs: Generating /boot/initrd.img-3.13.0-129-generic
  mkinitramfs: for root /dev/dm-0 missing nvme /sys/block/ entry
  mkinitramfs: workaround is MODULES=most
  mkinitramfs: Error please report the bug
  update-initramfs: failed for /boot/initrd.img-3.13.0-129-generic with 1.

  
  [regression potential]

  This changes initramfs creation for rootfs that are on nvme or lvm, so
  has the potential to break it for any system with its rootfs on either
  or both of those.  It is likely to only break initramfs creation, not
  system booting.
