Hi, Peter,
Thanks for the patience. I was still out of office last week, but now I have some news.

I've chopped the driver to use virt-dma (check [1]). It's not clean, but it works and one can see how the logic is changed. Unfortunately the mem corruption is still present on high loads. Maybe it's a coherency problem. I need more time on it. Will get back to you.
Cheers, ta
