What CPUs are you running on, and what sort of cache configuration are
you using? Presumably write-through caching also works fine?

I don't experience any breakage on a 4-way d-cache, but there have been
problem reports on other CPUs with 2-way. Specifically it seems to be a
cache colouring problem, bumping up the page size also corrects the
issue.

I'll see about reproducing and debugging it on a 2-way dcache..
