But mine is also a Lenovo Thinkpad, so that might be a thing. My system is a Lenovo Thinkpad X1 Carbon Gen4, which is a Skylake generation laptop. lspci output as configured in v4.9: root@miraculix:/tmp# lspci -vvvnnxxxs 1f.6 00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection I219-LM [8086:156f] (rev 21) Subsystem: Lenovo Ethernet Connection I219-LM [17aa:2233] Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Interrupt: pin A routed to IRQ 134 Region 0: Memory at e1300000 (32-bit, non-prefetchable) [disabled] [size=128K] Capabilities: [c8] Power Management version 3 Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D3 NoSoftRst+ PME-Enable+ DSel=0 DScale=1 PME- Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Address: 00000000fee00378 Data: 0000 Capabilities: [e0] PCI Advanced Features AFCap: TP+ FLR+ AFCtrl: FLR- AFStatus: TP- Kernel driver in use: e1000e Kernel modules: e1000e 00: 86 80 6f 15 00 04 10 00 21 00 00 02 00 00 00 00 10: 00 00 30 e1 00 00 00 00 00 00 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 aa 17 33 22 30: 00 00 00 00 c8 00 00 00 00 00 00 00 ff 01 00 00 40: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 50: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 60: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 70: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80: 28 00 00 00 08 00 00 00 00 00 00 00 00 00 00 00 90: 00 00 00 00 1f 00 00 00 00 00 00 00 00 00 00 00 a0: 00 00 00 00 01 00 00 00 03 10 03 10 00 00 00 00 b0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c0: 00 00 00 00 00 00 00 00 01 d0 23 c8 0b 21 00 00 d0: 05 e0 81 00 78 03 e0 fe 00 00 00 00 00 00 00 00 e0: 13 00 06 03 00 00 00 00 00 00 00 00 00 00 00 00 f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Attaching the .config. The laptop is running Debian sid, which is more or less "stretch" now. But I usually build my kernels on a Debian stable ("jessie") system if that matters. As for whether it works or not, I must admit that I haven't tested. Wired ethernet is not something I use on a daily basis on this laptop. Will test it when I find time, but sending this now so you have something to start working with. Thanks Bjørn
