Architecture: alpha

>Description:
        ddb(4) says:
MACHINE-SPECIFIC COMMANDS
     The "glue" code that hooks ddb into the NetBSD kernel for any given port
     can also add machine specific commands to the ddb command parser.  All of
     these commands are preceded by the command word machine to indicate that
     they are part of the machine-specific command set (e.g.  machine reboot).
     Some of these commands are:

   ALPHA
     halt       Call the PROM monitor to halt the CPU.
     reboot     Call the PROM monitor to reboot the CPU.

but neither "machine halt" nor "machine reboot" exists on alpha.

>How-To-Repeat:
        drop to ddb on serial console, try to halt or reboot
>Fix:
        add back the missing machine-dependant commands ?
