I don't see any references in your logfile to mounting or unmounting filesystems, but since it got as far as shutting down or trying to shut down systemd, they should be getting unmounted before the hang.
Most linse in your logs were truncated but this line implies you have sucessfully umounted all filesystems, after which a forced power cycle cannot corrupt the filesystems: Aug 27 16:14:02 lavoko-HP-Pavilion-Notebook systemd[1]: user@1000.service: Killing process 976 (systemd) with signal SIGKILL.
