Yes.  It is a *WELL* known problem that PC serial ports tend to put
out a long BREAK sequence while power is coming down, which kicks the
system into the debugger.

I don't know about NetBSD/pmax specifically, but I do know that
FreeBSD/i386 has a timeout value you can set via a config option to
tell the debugger to resume the system if nothing happens in a while.
Maybe it is time to look for that in Netbsd/pmax and add it if it
isn't there.
