    Subjectkernel crunch to a halt with e1000e driver
    From
    Date
    Hello guys,

    Latest linux git tree, noticed the e1000 driver no longer worked with my
    pci express nic. e1000e works but has the following bug...

    Problem: When system grinds to a halt when unplugging the cord from the
    nic.

    Let me know if you need any more info.
