Here is the problem: the tap (or tap2) driver is not supported in Xen upstream. So this is a hard to support from the ubuntu side. I wonder whether, when you check the blkfront messages from within an Oneiric domU guest, does it show barrier or disk cache flush being used? I would expect somehow to find out that barrier requests did not get used by the guest before (even though they probably have been offered by the tap2 backend). Now the frontend in Precise actually uses that feature and that could just show an issue that had been present in the tap2 backend all the time.
