Moving over to systemd folks for comment... If any messages appear at all (e.g., "watchdog did not stop" or "going down for reboot" or "rebooting"), they always appear after the delay. That is, if I see any messages, I know that the delay is over and the system will power down or reboot now. Please follow instructions at [1] (paragraph "Shutdown Completes Eventually") and attach obtained shutdown log.

Should I attach only the log obtained after a delayed shutdown or the one obtained in any case? Just for the delayed shutdown. Created attachment 1105005 [details] Shutdown log as requested in comment #3 Attached the shutdown log for a delayed reboot. I have got another shutdown log from a delayed shutdown (power down). Please let me know if it is required. Please, also specify the systemd version you are using. How frequently does this problem occur? I can't reproduce this, but I could backport some watchdog patches and provide you with the packages. Would you be willing to test those? One more thing you can do. 1) Enable debug shell (systemctl enable debug-shell.service). 2) When the shutdown hangs, switch to tty9 and execute "systemctl list-jobs" and attach the output to this bugzilla. 3) Disable debug shell. (In reply to Jan Synacek from comment #8) > Please, also specify the systemd version you are using. Unfortunately, I did not note the version number. I think I have had two regular upgrades to systemd since then, which were 222-11 and 222-12, so the version which was installed when I reported the bug was probably 222-10. > How frequently does this problem occur?

The problem has always occurred randomly, sometimes twice in a row, sometimes not even once in several days. However, ever since the upgrade to 222-11, I have not experienced the problem, but I can't know if it is gone for good. I don't know what the proper procedure is in such cases; perhaps the bug could be closed and later reopened if the problem occurs again? Ok, I'm closing this bug now. If it happens again, please also attach the output of "systemctl list-jobs" (described in comment 9). |
