Sounds like it may be an NFS mount that isn't there any more. Any process trying to access it will block and can't be killed (I think you can set a mount option in /etc/fstab or the command line to make it so if things get in this state you can kill them - see manpages - I think it's the 'intr' flag)[1]. These can be rather tricky to get rid of without rebooting...(sometimes if you recreate the NFS mount on the machine it's mounted from you can get there). If you have been using rumba and didn't use the unrumba command to unmount, learn to do so. <grin> > Any ideas?

Go ahead, reboot it. At least you can *schedule* it :-) It's uncontrolled reboots that are the problem. Stuart [1] the way it works *is* good behaviour in the usual case where a NFS server is rebooted, because clients accessing it will just wait for it to come back online and continue where they left off.
