Right now, I am running with LOCKDEBUG. I will add DIAGNOSTIC and DEBUG.

Not knowing much about kernel debugging, and since creating a core  
dump is not possible, what commands should I run the next time the  
dead-lock occurs?

I looked for info on www.netbsd.org, all I found was the "What Goes  
In A Problem Report" page (http://www.netbsd.org/Misc/pr-hints.html)  
probably need some updating.
