Description of problem:
Hi, 
since quite some time I observe a random pattern that the system does not shutdown immediately. Sometimes it works and sometimes it kills the X Server and stays in the console for some time (approx 3min timeout) until the shutdown process continues. 
I have no idea how to debug this since I don't have the possibility to access it via ssh. I already added systemd.log_level=debug systemd.log_target=kmsg to the grub.cfg. Let me know how I could give you information and I will do so.

Version-Release number of selected component (if applicable):
systemd-gtk-37-3.fc16.x86_64
systemd-37-3.fc16.x86_64
systemd-units-37-3.fc16.x86_64
systemd-sysv-37-3.fc16.x86_64

How reproducible:
random - no pattern detected

Make sure SELinux is permissive or disabled.
Save this script as /lib/systemd/system-shutdown/debug :

#!/bin/sh
mount -o remount,rw /
dmesg > /dmesg-shutdown.txt
mount -o remount,ro /

Make it executable. When you reproduce the problem, attach the dmesg-shutdown.txt file to this BZ. Thanks.
