At this moment, I was still able to access this machine through ssh tools, then
I tried to reboot on the other ssh connection, I got following message and ssh
service is gone:
Failed to issue method call: Did not receive a reply. Possible causes include:
the remote application did not send a reply, the message bus security policy
blocked the reply, the reply timeout expired, or the network connection was
broken.
Warning: Unit file of reboot.target changed on disk, 'systemctl --system
daemon-reload' recommended.
Then I checked the netconsole output, it was still look similar to <a href="show_bug.cgi?id=89568#c2">comment 2</a>:
