Same here, also system76 laptop. I think I get it after a failed suspend. I.e. close laptop lid, and it won't suspend. When I open the lid again, I have no network. Then I can't reboot. Factors that may impact is that I have nfs directories mounted (using autofs, so hopefully not mounted), and a bluetooth headset.
I noticed that when typing "sync" the terminal hangs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1441253 Title: hanging suspend job prevents shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1441253/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
