It used to be that "watchdog 0" in ddb disabled the watchdog, then when
we upgraded to 8.2 that stopped working.  One day I discovered (via
typo) that now just "watchdog" without a numeric parm disables it.  I'm
not positive that applies to the ichwd but it works that way for the
hardware watchdog on our arm platforms.
