Can't say much, I havent' looked at the cdvd code for months... mainly because I don't like the current code at all, but rewriting it is boring.
Basically the current threading code kind of works, but just because I'm lucky. I want to make a more robust code for it someday, but I can never seem to get myself into it.
I looked at those logs, and it seems to read something wrongly, because it starts reading different sectors than it's supposed to. I don't have the game so I can't test it myself, but I will see if I manage to convince myself and code cdvd a bit more.
