@ppshenoy, could you reboot with following kernel parameters and paste the screenshot (probably by camera) when it stuck at shutting down and syslog file?
1. replace following line in your /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with: GRUB_CMDLINE_LINUX_DEFAULT="systemd.log_level=debug" 2. run `update-grub` to update grub config 3. reboot with aforementioned changes 4. shutdown and take a picture of messages printed in the console mode. 5. attach both the picture and syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861645 Title: PC fails to shutdown.
