They weren't properly sent resulting in the guest crashing (https://bugzilla.redhat.com/show_bug.cgi?id=824641) The fix is in the backend (blkback) and the frontend has some extra WARN_ON added to diagnose similar issues like this in the future. Or if you prefer - I can stick those two patches in my tree and send them to Linus in my git pull this Friday with your Ack-ed by tag. Thanks!
