    I217V on Z87 Motherboard Hangs with e1000e Linux Driver until Clear CMOS

    Random12

      I built a Linux machine around an ASROCK Z87 Extreme4/TB Motherboard with an onboard I217V Ethernet port.

       

      Behavior is the same on recent Mint/Ubuntu and Fedora distributions with up to date e1000e drivers.

      On booting from a clean state the Ethernet port is recognized and seems to work fine.

       

      Once I do nearly any sort of shutdown, suspend, or restart the port is hung on reboot or resume.

      The port remains hung even after a complete power cycle and reboot. The port remains hung after

      entering UEFI BIOS and reloading all UEFI defaults.  Opening the case and physically clearing CMOS resets

      the port to a working state.

       

      Can anyone help? Is there any sort of linux utility that would allow me to reset the port? Opening the case every time I need to reboot is a major pain.

      lspci output follows. If anyone can help, let me know what other output or information would be useful.
