Title:
  Unable to unpack initrd.img-4.4.0-36-generic

Status in initramfs-tools package in Ubuntu:
  New

Bug description:
  I'm filing a bug report against initramfs-tools because I don't know
  which package is better. The initrd file produced by "update-
  initramfs" cannot be unpacked with cpio:

  $ file /boot/initrd.img-4.4.0-36-generic
  /boot/initrd.img-4.4.0-36-generic: ASCII cpio archive (SVR4 with no CRC)

  $ stat /boot/initrd.img-4.4.0-36-generic | grep Size
    Size: 45048327 Blocks: 87988 IO Block: 1024 regular file

  $ cpio -id < /boot/initrd.img-4.4.0-36-generic
  44 blocks

  $ tree ./
  ./
  └── kernel
      └── x86
          └── microcode
              └── GenuineIntel.bin

  $ du -sh kernel/
  36K	kernel/

  On another machine, the initrd (same version) is a gzip'ed archive
  (this one isn't) and unpacks just fine. On this machine, with this
  initrd, I also have a problem as explained in bug 1638983, so it could
  be related. Decided to file another bug for initrd.
