Description Adam Williamson 2020-11-30 18:57:33 UTC 
In current Rawhide, with systemd-247-1.fc34, systemd (pid 1) frequently segfaults on system shutdown or reboot.

openQA is running into this in several tests. Most obviously base_service_manipulation, which involves enabling/disabling services and rebooting several times, e.g. here's one such failure:

https://openqa.fedoraproject.org/tests/732376#step/base_service_manipulation/11

but it's also hitting other tests too sometimes. Several tests have to do a clean shutdown so they can upload disk images for other tests to use, and these are frequently hitting this bug too.

damjan says it's likely upstream issue https://github.com/systemd/systemd/issues/17768 that should be fixed by https://github.com/systemd/systemd/pull/17785 , but this is such a critical issue I don't really want to backport an unreviewed PR myself.

Proposing as a Beta blocker per "It must be possible to trigger a clean system shutdown using standard console commands" - https://fedoraproject.org/wiki/Basic_Release_Criteria#Shutdown
Comment 1 Adam Williamson 2020-11-30 20:10:48 UTC 
In https://openqa.fedoraproject.org/tests/7324005 I believe we hit a segfault on `systemctl isolate graphical.target`.

Should be OK now.
