eth0 keeps going back to 100mbps

  • It doesn't look like they install/upgrade anything.

    Still the same errors in the GUI on the plugins tab.

  • After the 3.2 backports kernel install I did a reboot of the server. It came up with eth0 at 100 again, so I switched it to 1000 and once again it switched itself back to 100 after a few seconds.

    I figured I should check that it's actually using the 3.2 kernel and it doesn't look like system is using the 3.2 kernel even though the install looked successful.

    root@openmediavault:~# cat /proc/version

  • Try to install it manually via CLI:

    echo "deb squeeze-backports main" >> /etc/apt/sources.list
    apt-get update
    apt-get install -t squeeze-backports linux-image-amd64 linux-headers-amd64

    After a reboot you should be at the backports kernel.

  • Actually I don´t think it is a hardware problem. But it would be interesting if a new mobo (same one) would fix the problem.
    Would try a new driver for those cards.

    Off: Got a similar error with my backports kernel... Only solution was to do it manually. And this is not the first time i read that the button did´nt install the kernel properly. Maybe the button needs to be redone from aaron...

  • Are you sure that your board has two 82573V interfaces? Lots of manufacturers put one 82573V and one 82573L on their boards.
    I doubt that the drivers are the culprit, Intel E1000E drivers have been included in almost any Linux distro since a long time. Have you ever been running this board with another OS, i.e. Windows? If it doesn't fall back to 100mbit when running Windows then the hardware should be ok.
    Do you run the latest bios firmware version? Sometimes it helps to bring it up to the latest version in such situations.

  • Yes, you are correct, this board has one of each. I had to install the e1000e drivers to get the NICs to work after initial installation.

    dpkg -i e1000e-2.6.32-5_2.3.2_amd64.deb

    The last OS on the machine was a variation of CentOS. Both NICs worked in gigabit mode. I have had a few others on there over the years and have never had an issue with the gigabit NICs.

    The board is a Super Micro PDSM4+…/xeon3000/3010/pdsm4_.cfm
