Hi, one of my nodes in my cluster has an issue after rebooting. The mainboard of this node is a Supermicro X10SBA with two network interfaces (eno1 and eth1 in Proxmox). Interface eth1 is not active, and only eno1 is bridged with vmbr0 and all is working fine so far when networking is up.

Anyhow, when I reboot the server, in 50% of the reboots it starts up without a network interface. The node does not appear in the unifi device list, and is not accessible via ethernet. When I then press the power button to shutdown the server and restart it, there's a big chance that it now starts with network connection. I am not sure where to start searching, I already went through some BIOS settings, but did not find any solution.

This link contains the comparison of two log files: one for a boot without ethernet, the second one for a boot with ethernet. The reason for this behavior must be somewhere hidden in them:

Maybe someone could help and push me in the right direction, or possibly provide a solution. Thanks!
