Sucks. What's making me wonder here is, address decoding of address 0x0 actually shouldn't fail, since window 0 includes this address. For now, I have pushed two new commits to my public git, adding more debugging output for decoding window logic and interrupt case as well as decoding window permission fix and changing from FETCH_ND to programming the first DMA descriptor's values manually. In the long term, I probably should try to get access to some appropriate hardware myself. This is rather a quiz game than actual bug tracking.
