When i reboot the system shutdowns properly (prints Rebooting...) but then just hangs with no activity (screen blank, disk diodes dead,etc).

If it's needed, i'll provide the exact hand written version) I did some discussion with the author of MADT and apparently the panic is necessary. You should disable acpi early with: hint.acpi.0.disabled="1" in loader.conf. Your system is older and should work with acpi disabled just fine. -- Nate
