Reboot via dBus causing full shutdown on Ubuntu Core

Hi All - wondering if anyone can shed any light on this.

Running the latest Ubuntu Core image on Raspberry Pi CM4 hardware.

Triggering a reboot with the following command, but it seems to be resulting in a full hardware shutdown, rather than reboot (assuming that, because the system doesn’t recover from the reboot - but the activity LED is flashing when it’s in this semi-shutdown state):

dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 “org.freedesktop.login1.Manager.Reboot” boolean:true

This is up there with the most serious issues a headless / remote device could have, because it will require a site visit to resolve.

Would appreciate any insight / additional testing that could be done to figure this out.

The hardware watchdog is enabled on the CM4.

sorry, this system is actually running Ubuntu 20.04.4 LTS (GNU/Linux 5.4.0-1069-raspi aarch64)

Hey @brendan.carroll,

This seems like a bug to me. I would recommend creating a bug report here with all the logs attached from the device. => https://bugs.launchpad.net/ubuntu/focal
