Hi All,

Once a day my TP board totally lost the ethernet. Is there any way to find why?

LP 4G/64G, Ubuntu 16.04.3 LTS (Linux panda 4.4.0-98-generic), used as server (no desktop, only remote ssh).
Power is good (2A thru the ups), large (realy large) heatsink used, no keyboard/mouse/display connected.

Reasonable, I hope, part of /var/log/syslog.1:

Code: Select all
