October 9, 20241 yr I have replaced onboard NIC (Realtek) with Intel 2.5G pcie but can't make it works. I see "Device "eth0" does not exist" when Unraid starting. Removing network.cfg does not help. I have found this in logs: Oct 9 16:29:29 Tower kernel: Copyright(c) 2018 Intel Corporation. Oct 9 16:29:29 Tower kernel: igc 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible Oct 9 16:29:29 Tower kernel: igc 0000:02:00.0: PCIe PTM not supported by PCIe bus/controller Oct 9 16:29:29 Tower kernel: igc 0000:02:00.0 (unnamed net_device) (uninitialized): PCIe link lost, device now detached I have tried to play with BIOS settings but without success tower-diagnostics-20241009-1635.zip Edited October 9, 20241 yr by Vitek

October 9, 20241 yr Author I have only one PCIe slot on this motherboard, NIC works in PC with windows
