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)

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