moby: Can't start with systemctl - actually, no errors, it just hangs on everything

I seen the issue template, but I can’t give nothing of wanted. Only a fiew things.

1. I’m on fully upgraded ArchLinux, 64bit processor
2. Installed docker via pacman pacman -S docker - no problems
3. Enabled via systemctl enable docker.service, reboot
4. Added my username to docker group sudo usermod -aG docker $(whoami), reboot
5. Just hangs on docker info, docker version and even when systemctl start docker, etc.
6. The result of systemctl status docker.service is Active: activating (start)

● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
   Active: activating (start) since Mon 2016-06-06 04:25:51 EEST; 27min ago
