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 > something newer might help. 10rc2 has a fairly number of the problems > fixed and a few new ones (eg it won't boot on some boxes) but might be > useful to at least see if you are chaasing a fixed bug 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 213484 1 - Live 0xe02ad000 > > subfs 12288 1 - Live 0xe01c4000 > > This is ARLA stuff ? 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.
