    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.
