Interesting read and kind of a tough problem to find out about the hard way...

Anyway: per that knowledgebase article, I believe they're simply saying it's up to you to make sure your uncached and cached data are stored in separate memory regions (at least cache-line-size).

If all of your accesses to your DPRAM are via alt_remap_uncached() pointers, I don't think you should have a problem. Maybe you're running into something else.
