Comment 28 for bug 1871538

Yeah, sorry, I don't think that's a reproducer for the bug. You killed dbus, gdm and everything else, and they obligingly died on you. :)

My feeling is that this bug is about a deadlock that somehow happens when dbus and/or systemd are reloaded, possibly at the same time. It looks like dbus stops responding to systemd, and so when it calls GetNameOwner() to be able to watch type=dbus units, it gets no reply and then decides to kill all type=dbus units, which is a lot of things. If that's right, it's most likely to be a dbus bug that it can get into this state. But I'm personally at a bit of a loss as to how to approach it without being able to reproduce.
