Hi Ozzloy, from what I see, you are using the Linux 3.2.0-4-amd64 kernel that is the oldoldstable kernel. https://packages.debian.org/search?keywords=linux-image-3.2.0-4-amd64
Is there any reason why you are using this kernel version? Can you try to reproduce the bug with a more recent kernel (3.16 or 4.9)? I can not boot on the 3.2.0-4-amd64 kernel on my test platform (Debian 9 KVM), and so I can not try to reproduce this issue that may be related to systemd — kernel interaction. Faustin
