No

Driver version: 7.3.21
Kernel Version: 3.5.0-17-generic

After fresh install of Ubuntu 12.10 the driver only gets 10Mbps. Setting options setting configuration either via the command line or in a /etc/modprobe.d/ file doesn't apply those changes.

(And if you could point me to a patch for the pm_qos_params bug that prevents compiling of the latest driver that would be swell.)

    Have you tried in-kernel e1000 driver?
    e1000 out of box driver has end of life.

    I'm using the in-kernel driver, which is version 7.3.21. I'd love to try to use the official one but I can't compile it and can't find the patch.

    What is the link partner your device is connected to?
    Please send me the dmesg log and 'ethtool ethx' output.

    Was it working before on this system before you upgrade/updated with Ubuntu 12.10?

    By link partner do you mean what it's connected to? If so, that's a NetGear gigabit switch. I tested the port that it's connected to by connecting my laptop to it and that indicated and supported gigabit speeds.

    And I haven't been able to get gigabit working on this system except when I first got it. It had Windows Server 2003 on it, so it was using a completely different driver.

    Attached is my dmesg log from my latest boot.

    Sorry for the delay?
    Do you still have this issue?

    What if you run 'ethtool -r ethx'? or disconnect/connect cable? Does it help?
    Has it ever link to 1Gig before while using your Linux system?
    Have you tried any other link partner?
    please send me the output of
    ethtool -e ethx
    ethtool -d ethx

    Running ethtool -r eth0 doesn't help, neither does disconnecting and reconnecting the cable. It ran at 1Gbps when I first bought the machine before I did a fresh install of the operating system.

    I tried connecting it directly to my router (Apple Airport Extreme) and it's still indicating 10Mbps.

    Attached is the output from ethtool -e eth0

    Here is the output for ethtool -d eth0

    Thank you for your time in looking into this.

    Would you also please send output of ethregs?

    I'm afraid I don't have ethregs installed. Where can I get it from?

    Alright, found ethregs and installed it. I've attached the output

  • Have you tried with a different cable?

    Yes, I've tried different cables, verifying that each cable supports 1Gbps using my laptop's NIC.

    Can you please attach ethregs output after issue occurs (when cable is connected))
