    D2500CC:  LAN bricked




      I have a new replacement of a defective D2500CC motherboard. It was explained in this thread:  D2500cc : strange tic-tac sound in off


      This new motherboard was working right 2 days, and then suddenly the first LAN was not recognized. Now inside the BIOS there is not Lan1 mac address in the section "System Information".  Just there is the MAC address of the Lan2


      In Linux, I have this error:

      e1000e .... : The NVM Checksum Is Not Valid

      e1000e: .... failed with error -5


      in the Lan1 connector of motherboard there is one green light active, so I believe still is alive.

      And also I can see the device in the SO: 


      # lspci -vvvv | grep Ethernet

      01:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection

      02:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection

      I'm reading many informations about the problems with 82574L, in example:

      e1000e interface hang on 82754L

      Unbricking an Intel Pro/1000 (e1000) network interface

      although I'm not an expert at all. If I understand well, maybe the EEPROM was deleted or damaged.  That's right?


      - Is there some way to restore my LAN device?

      - Is there some easy guide to flash a new LAN firmware from an USB boot to solve this issue with Linux?


      Please, give me some support to know the right way to solve this. Or to know the right firmware to download and the procedure to fix this error.


      I'm reading tons of informations around this issue, and I don't know exactly the right thing to do.
