Public bug reported: Expected: System reboots/powers off.
Actual: System hangs with the plymouth bootsplash with the Kubuntu logo. Pressing escape shows `[OK] Reached target Reboot`. `journalctl -b -1` shows at the end. ``` May 28 16:33:21 jordan-ThinkPad systemd[1]: Shutting down. May 28 16:33:21 jordan-ThinkPad systemd-shutdown[1]: Syncing filesystems and block devices. May 28 16:33:21 jordan-ThinkPad systemd-shutdown[1]: Sending SIGTERM to remaining processes... May 28 16:33:21 jordan-ThinkPad systemd-journald[454]: Journal stopped ``` Letting the computer continue to idle, an error message shows up. I've attached a picture because the error message does not show up in any logs. Possibly a duplicate of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872817, though the other user did not mention the same symptoms.
