    This is a known kernel issue:

    http://bugzilla.kernel.org/show_bug.cgi?id=2839

    Also see the Fedora issue on this:

    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121902

    Basically there are two things you can do:

    a) Either downgrade to the i586 kernel...
    b) or upgrade to a bleeding edge kernel (one of Arjans for instance,
    although I'm not a 100% certain that the patch that fixes this is in his
    kernels)
