You're right, thanks Ed. His "when it comes back up there is no crash file" is what threw me for a loop. Stephen, does the problem *only* happen when using the -d flag, or does the system lock up on reboot in general? If the latter, try using one or both of the following sysctls: hw.acpi.handle_reboot=1 hw.acpi.disable_on_reboot=1 If the lesser, I've no idea. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
