I want to save some energy, so I set the power control of all my PCI devices "auto". But if I do this with my unused ethernet device, this will crash the server if I change afterwards some network settings through the WebGUI (or execute ethtool as in the following example):   In Unraid: # lspci -nn ... 07:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller I225-LM [8086:15f2] (rev 03) # ethtool -i eth0 driver: igc version: 5.15.46-Unraid firmware-version: 1057:87
