I've committed a fix for the LOCKDEBUG problem on the CS20/DS20L, and it
has been pulled up to the netbsd-5 branch. One of the things that
LOCKDEBUG will do is to limit how long the cpu spins waiting for a lock,
so should eventually panic instead of hanging forever deadlocked. It also
keeps more information about the locks, including which cpu holds the lock
and the address where the lock was acquired.
