      Just spitballing here, but has anyone else used this ASRock mobo (with Intel X550-AT2 and i210 NICs) with xcp-ng 8.3? I've been experiencing a variety of seemingly incongruous NIC connectivity problems. All the ports seem to function normally under a standard PopOS install, so doesn't seem like a hardware failure, but I can't rule that out.

      Unfortunately, due to the nature of the issue I can't provide any logs. I'm not well versed in the xcp-ng network subsystem, but one of the more consistent issues was SSH connections timing out after about a minute when connected via one vlan to one of the X550 ports but perfectly stable SSH connections when connected to a different vlan on the other X550 port.

      The other head-scratcher is the 1Gb ports becoming active only intermittently after various reboots. I know this sounds like a hardware failure, but I thought I'd throw this up here just in case anyone has had a similar experience.

      Thanks!

        Hi,

        First, I would check to have all firmware fully up to date, including for the NICs. Might be hardware or driver issue.

          I would also suggest making sure you have enough airflow over the heatsinks on the board, particularly the ethernet chipset, it may be on the edge of its heat threshold.

            Thanks for the tips. All those items checked out. After a bit more troubleshooting involving a nearby switch and my VLAN routing, things are working a little more consistently, so I'm going to chalk this up to a routing issue elsewhere in my network. I'm just not used to a NIC turning off the link light if there's not a valid route.
