Actually, refreshing my memory in the comments here, others are also reporting that issues for 1b4b:9230 persist, but they're different than the problem we're trying to fix here and suggest either broken hardware or broken driver (or both). As suggested previously, if you're not getting DMAR faults, file a new bug.
