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.
