It appears that history repeats itself. Once (July 2013) a similar issue was reported here, by different user: http://lists.freedesktop.org/archives/systemd-devel/2013-July/012283.html
I'm also using Arch Linux, systemd-207, linux-3.11.2. On shutdown and reboot, user@0.service occasionally freezes my system until it times out and gets killed. Steps to reproduce: 1) Boot 2) Login 3) Execute either systemctl reboot or reboot or shutdown -h now or whatever. I've went through the steps here, to get a proper shutdown log: http://freedesktop.org/wiki/Software/systemd/Debugging/#shutdowncompleteseventually And, the shutdown log can be found here: http://pastebin.com/wbr04AQw The actual lines related to issue: #2223 [ 74.387130] systemd[1]: Got D-Bus request: org.freedesktop.DBus.Local.Disconnected() on /org/freedesktop/DBus/Local #2224 [ 163.814925] systemd[1]: user@0.service stopping timed out. Killing. #2225 [ 163.815447] systemd[1]: user@0.service changed stop-sigterm -> stop-sigkill #2226 [ 163.816063] systemd[1]: Received SIGCHLD from PID 326 (systemd). #2227 [ 163.816093] systemd[1]: Got SIGCHLD for process 326 (systemd) #2228 [ 163.816153] systemd[1]: Child 326 died (code=killed, status=9/KILL) #2229 [ 163.816158] systemd[1]: Child 326 belongs to user@0.service #2230 [ 163.816171] systemd[1]: user@0.service: main process exited, code=killed, status=9/KILL #2231 [ 163.816183] systemd[1]: user@0.service changed stop-sigkill -> failed I currently haven't found out a pattern for this. I have attempted to quit some processes before initiating the shutdown/reboot, but the result is random. About 95% of shutdowns/reboots it will be a long one. 3% it will be noticeably longer than the quickest one, but shorter than the above one. Remaining 2%, the shutdown will be very quick. It also happens if I get to log in console screen and Ctrl + Alt + Del, like, I perform an ASAP shutdown after boot. In case anything more is needed, please ask. -- Toms Seisums - (+371) 26431391 May the force be with you, always!
