As we talked in #ext4, I've downloaded that big torrent (14GB) with nodelalloc. Hash check was fine for such a big torrent which also had so many peers, so I'm inclined to think that nodelalloc does indeed make the problem go away. Whatever's wrong, it's definitively delalloc-related. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
