Turning mpsafevm off prevented my machines from completely locking up, but they still entered a mostly useless state where simple commands such as 'ps' or 'ls' could take a minute or more to execute. However, since the complete lock-ups only happened when I provoked the machine (never during regular operation) I continued to run with mpsafevm enabled. I'm not in a position to test the 'dd' trick right now, but I'll try to do that later tonight to see if it still locks the machine up. /Daniel Eriksson
