    Yes, it's arpwatch.

    In fact there are 5 init scripts which could trigger the bug. One of
    them (powersaved) runs fuser directly. I've traced the other shutdown
    scripts via "sh -x -v" and none of them appears to call fuser.

    The line from /etc/init.d/powersaved is

    for X in $(fuser /proc/acpi/event);do

    This, together with your comment about USB + SCSI bug fixes below
    sounds as if we really want to use 2.6.10rc2 (if it boots), because
    having a machine crash during normal work is a lot worse than on
    shutdown.

    nnpfs is the kernel-side portion of the AFS Client, subfs is from the
    submount package (km_submount) from SuSE 9.1. It allows users to
    insert cds and change to /media/cdrecorder to access them and also
    allows the user to eject the cd as soon as there's no process in
    /media/cdrecorder any more. See http://submount.sourceforge.net/

    Thanks for your help!

    I already mentioned to Andrew Morton that right now it seems prudent
    to continue with 2.6.10rc2 (to get rid of the USB and scsi problems)
    and try to convince __d_path to give a conclusive hint about the
    culprit.

    Kind regards
         FDF
