Congratulations!  Hopefully, the work on the Daystar PowerCache will 
achieve similar results.

Sorry, don't know how to fix this ;-)

I think that this is a result of the "dumps on sd??" or whatever line in 
your config file.  If you ever get /netbsd itself to dump core, it will 
dump to the dump device (it's actually quite scary when it happens; I've 
done it once).  Perhaps it is improperly specified in your config file.  
Of course, I'm not too knowledgable about this little area of system 
administration, so perhaps someone with a little more experience will 
speak up. 

Later.
