Shutdown becomes a reboot

[Tanduvil]

Hello community,

I run OPNsense 21.1.6 on a Jetway JBC390F541XA-19-B with 6x NICs.

I noticed that when I do
- SSH the system and shutdown the system with "shutdown -p now" OR
- shutdown the system in the OPNsense webGUI via power > power off OR
- simply press the power on/off button on the front of the appliance

the system never shuts down completely, instead, after 3 seconds, it is rebooting.

I witnessed the same behaviour even when I completely disconnected all lan cables from all 6 ports.

No way of shutting down, just rebooting.

FYI: I was also checking the reboot function, it of course works as expected.
Do you have any hints for me what to change to successfully power off my system when it is needed?


Thank you,
Christian
