    I just built a kernel with that latest stack-fix patch in it too, but
    haven't rebooted to it yet. I read that as being moderately
    important in some cases although I don't think I've encountered that
    particular case yet. Was this in fact a good idea for me?

    That would I assume need a null modem cable, and what do I run on the
    firewall? Minicom? Or is there something better that can just grab
    and log without being interactive? Its a rh7.3 box with a 2.4.18 era
    kernel. I'd update that, but its not broken. :)
