MCU don't go into reset state after Linux host was shutdown

[FranzPVal]

I have a strange behavior using a M8P equipped with a CB1 and the latest 2.1.2 image.

If I shutdown the host - for example using Mainsail UI "Host Control" -> "shutdown" the STM32G0 kept all steppers, fans, heaters in the current state. There was no MCU reset or whatever. After a night long the steppers and fans (not only the hotend fan) was active. So I test this: The MCU don't go into a reset or shutdown-state at all. I don't find any general information about this.

Tested:
Service /etc/init.d/klipper_mcu stop command stopping the service, but don't have any effect on the MCU state.

I can confirm this behaviour on 2.2.1 . Shutdown hurakan and steppers remain active.

Can confirm with 2.2.1 minimal as well
