    SubjectRE: 1000xf bus problem
    Date
    From

    If you mean dmesg it says this:
    e1000: 0000:0d:02.0: e1000_probe: (PCI-X:100MHz:64-bit) {macaddress}

    That's weird... dmesg shows one thing, lspci shows another, and my data
    transfers seem to point to the lspci info...

    Any idea which I should trust?

    what is the dmesh output of e1000 ? it should show you what the card
    itself detects (at least the newer drivers since 7.0.x all do). This may
    provide some clues as to what the card has detected.
