System hangs at reboot/shutdown


#1

Hi altogether,

after performing a clean install of Lubuntu 18.04.2 LTS, 64 bit, I experience shutdown/reboot problems. The system hangs at a specific point.

After deactivating plymouth (“noplymouth” instead of “quiet splash”) I was able to find out where the system hangs.
The last entries are as follows:

systemd-shutdow [1]: 12 output lines suppressed due to rate limiting
systemd-shutdown [1]: Syncing filesytems and block devices
systemd-shutdown [1]: Sending SIGTERM to remaining processes
systemd-journald [284]: Received SIGTERM from PID 1 (systemd-shutdown)
systemd-shutdown [1]: Sendig SIKILL to remaining processes …
systemd-shutdown [1]: Unmountig file systems
EXT4-fs (sdc1): re-mounted. Opts: block_validity,barrier,user-xattr,acl,errors=remount-ro
systemd-shutdown [1]: All filesystems unmounted
systemd-shutdown [1]: Deactivating swaps
systemd-shutdown [1]: All swaps deactivated
systemd-shutdown [1]: Deactivating loop devices
systemd-shutdown [1]: All loop devices detached
systemd-shutdown [1]: Detaching DM devices
kvm: exiting hardware virtualization

So the kvm thing seems to be the culprit.

Does anyone know what to do?

The whole thing is a bit odd as I have a pristine system and everything should work perfectly.

@Rosika,
I don’t know how to help you but this might be the bug you are getting?

Hi,
tnx a lot and sorry for the belated answer.
Yes, the link you provided refers to the very phenomeneon I encounter.

In the meantime I use the command
shutdown -H -P +0
to power down my system. This at least works without any difficulties.

Greetings.

Hi Rosika
Have you tried the repair option when you reboot? if you get the advance options and try a repair from there. I am almost certain I saw this on its Foss by @abhishek as I learnt how to do it from it although I use mint it worked
