That use to be pretty standard for a certain vintage of machines with dual processors (not dual cores, but separate CPU chips). One processor couldn't be sure the other one was done so they took the fail safe way of requiring physical interaction rather than risk one processor killing off some important shutdown work the other was doing. I haven't seen that problem since several releases (and I only have one dual CPU machine left). I think Dell had some other method for those machines. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
it might also be of some help to try to manually do what init, et al [s|w]ould be doing (nice vitriol from both sides about reboot/init/shutdown/whatever being the only acceptable way to handle a machine, by the way. super helpful). if feasible, I'd login cd /etc/init.d/rc.$current_runlevel + and run something of the ilk: for i in K* ++ do ./$i stop done and keep cycling down through run levels, looking for an init script that isn't quite shutting down correctly. apart from that, then look in /var/log/message for hints, perhaps do a dmesg and if things get really desperate try running strace on shutdown -h now, probably from within a 'script' session to capture all the system calls (and it will be pretty fugly, I suspect) + -- you'll have to either know or get current runlevel... should be easy enough to start with 'egrep -i initdefault /etc/inittab', then remember for the next level down. I'm also not entirely sure of this path, it seems like it's right, but it could be /etc/rc.X. These are just suggestions, of course, I don't recall having this problem on a machine in recent history.. and any older ones I had this with I chalked to POS hardware and moved on to something more recent.

Well, have a look at http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plai... and search for "Dell". Some models need the kernel option reboot=bios and some reboot=pci. Perhaps you have found another not yet included model that needs such an option.
