Thank you for the detailed investigation. I think this is unlikely to be a pmap prolem, since the assertion is concerned with software state - CLEAN and DIRTY are very definite states set by UVM. The pmap only comes into play if the page's state is UNKNOWN. The NFS changes on yamt-pagecache are unlikey to help either, as you discovered. I need to think about this one more.
Thank you for your comment! I'll keep trying to figure out what goes on. rin
