Created attachment 613875 [details] systemd shutdown log during poweroff Description of problem: During shutdown initiated with "poweroff", a minimal F17 installation in a VM may hang for 90 seconds with a black display. Version-Release number of selected component (if applicable): dbus-1.4.10-4.fc17.x86_64 kernel-3.5.3-1.fc17.x86_64 systemd-44-17.fc17.x86_64 How reproducible: Fairly reliably hangs for 90 seconds after "poweroff". Steps to Reproduce: 1. Complete a minimal F17 install in a VM as in Bug 845329, Comment 5. 2. Complete a full update and reinstall grub2 as in Bug 845329, Comment 6. 3. Reboot. 4. Poweroff. Actual results: May hang with a black display for 90 seconds during shutdown. Expected results: Shutdown completes without a hang. Additional info: I may have seen a hang during reboot. Removing "quiet" from the kernel command line seems to prevent the hang.

nm-dispatcher is forked off dbus apparently, and is unwilling to die on SIGTERM. It will thus delay shutdown. Reassigning to NM. (as a side note: would be cool to have nm-dispatcher as a natvie systemd service, as NM itself is too. That way things would be a lot more obvious, as people wouldn't blame D-Bus for one of its clients not terminating cleanly.
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
