Losing Network within 24hours uptime

[Zeroengel]

I have a new unRiad build and have been having issues with loosing network connectivity randomly. At first it was every couple days then anywhere from 24 hours to a week and now it is about every 18-24 hours I loose connectivity. I have been using solar putty and ssh in to monitor. Any help would be great.

[Squid]

I would try a different port on the switch if only to rule it out.

[Zeroengel]

Im bypassing the switch and will keep an eye on it.

[DeathStar Darth]

I have been having similar disconnects recently. Below is the last entries from my last syslog where it happened over this last wknd whilst I was away.
I see ASUS m/board in both cases, but very different board at that, and both running Nvidia.

 

A quick google throws up  varied references to "RIP: 0010:dev_watchdog" type error - e.g. https://bugzilla.kernel.org/show_bug.cgi?id=199783 but as of yet I've not read about anything conclusive as to cause/resolution.

Just by way of a 'how frequently does this happen'... I had this happen again overnight

 

After the trace, the log is then filled with a looping set of errors
