- I am upgrading my SS10 clone from netBSD 2.1 to 3.0 and while doing so,

- Are these errors in the CPU cache?

	Nope.

- Or do I need to replace one of my normal ram modules?

	Yup.. The memory error message above suggest that it's
the  module at J0304 on the main board.  Try removing/replacing
that module, and start stressing the memory system again.. I
suspect the errors will be gone.
