I've just replaced my KA630 with a KA650.  This is much nicer. 
Unfortunately some things don't work.  First, my TK50 is totally
unusable.  I think that this is due to hardware and not NetBSD because I
can't boot off it.  I also have a problem with my QDSS.  It passes all
the power-up diagnostics and works fine until I use it heavily in X. 
Then the QDSS driver reports bus errors during DMA.

So, does anybody have any suggestions/ideas?  I don't care too much
about the TK50 (though it'd be nice), but I do care about the QDSS.  Has
anybody else successfully used X with a QDSS and KA650?  Is there some
simple modification that I need make to get things to work?

(Geez... couldn't DEC standardize Q-bus somewhat so that these things
don't happen?!)
