Comment 5 for bug 1638983

I don't know if this is related, but the initrd looks broken, though the system obviously boots fine (encrypted root). I tried running update-initramfs, but it's the same:

$ 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/

So, where's the rest of the 45MB? Why isn't it gzipped? How does the system boot without cryptsetup in initrd?
