[TriLUG] 'reboot' doesn't

'dmesg' says that the ACPI modules loaded.  There's 60
lines of ACPI-related messages in the bootup messages.
None of them look bad, most of them have to do with
routing IRQ's.

'shutdown -h now' shuts down and turns the power off.

'shutdown -r now' does the same thing that 'reboot' does...
It shuts down subsystems, kills processes and then prints
"Restarting system" on the console.  But it does not reboot.
