    SubjectRe: e1000e: NIC not working (after resume?)
    Date
    [Crossposting to e1000 mailing list]

    I have a Dell Latitude E6400 which has a network card supported by the
    e1000e driver. Often (I think after a suspend/resume cycle), the network
    card does not work at all: the NIC is correctly seen by ifconfig, but
    running ethtool just returns: "No such device". dhclient -v gives the
    impression that it's correctly sending out DHCPDISCOVER packets on the
    NIC, but a tcpdump running on the same machine does not see any packets
    going out.

    I'm using Debian's 3.0.0-3 kernel (corresponding with Linux 3.0.3).

    Full lspci, .config and dmesg output at
    http://artipc10.vub.ac.be/~frederik/e1000e/

    Here is some relevant summary.

    How can I find out what is going wrong?
