Umm, maybe you are suffering from the well-known problem discussed several
times before..  Apparently, there is some hardware problem in the sun4c
MMU which is triggered by NetBSD 1.6 kernel code.  AFAIK, there still isn't
a good fix for the problem.  All my SS1's became completely useless the
day I upgraded them to NetBSD 1.6.  There's a patch which makes the systems
quite stable, but it also slows them down to 1/4 crawl.

It's a pity - I've got four SS1's / SS1+'s, but they are quite useless now.
