Hi hypper,
you can watch the command journalctl see the log messages. More information with "man journalctl" and here:

i know journalctl, but i couln't find any message from the shutdown process. maybe i have to dig deeper into it.

You may try:

Code: [Select]

journalctl -b -1 -n250where -b would show you the journal of the current bootup and -b -1 the journal of the one before. With -n250 your journalctl will show you the last 250 lines only. This is enough on my system to include every message from the system shutdown, the value on your system may differ a bit.

If it's ok for you that you have to see all the messages of the system-start too, change the /etc/default/grub like

Code: [Select]

GRUB_CMDLINE_LINUX_DEFAULT="quiet systemd.show_status=true"
systemd.show_status=true is the important thing to see messages.

Perhaps this article: "Diagnosing Shutdown Problems (http://freedesktop.org/wiki/Software/systemd/Debugging/#index2h1)" in the documentation might be helpful.
