Hey guys I have some HP DL 560 Gen10's that have dual onboard Broadcom 10G copper network adapters which are throwing call traces on Proxmox 7.2 at every boot. Networking is still working, but not sure if this could cause other issues. It seems to only happen at boot and there are 3 of them in total.
