Hi,
I do not get kernel temperature messages, but I have exactly the same symptoms.
My raspy only has bind9 installed and acts as dns/dhcp server. After an unspecified amount of time aka over night, it just disappears from the network. DNS requests get answered after I "woke" it by SSH to its ip address.
My journal has no unusual entries for hours before my login at 08:23 (start lines for system info):

I have set in /etc/systemd/system.conf the log level to debug, maybe that brings more info.
The behavior only started some weeks ago, before that it was fine. I update via pacman once a week.
Any ideas?
