Network manager ASLEEP on UC 20 rpi

Hi.

I am using network-manager from beta to build the custom UC 20 image for rpi. During some of my testing ssh went down. Reboot did not help. I managed to connect over wifi later on and from logs I found out that network manager went to ASLEEP state.

How can that even happen? Is there a way to disable this functionality? I did not manage to get all the logs because we have log rotate on.

This suggests that something requested NM to be disabled, eg. by running nmcli networking off?

Hmm, ok, got it. I thought sleep was called going by the resulting state.
