I was experiencing the same with Ubuntu domU's just some months before.
The only solution was to migrate from EXT4 to EXT3 - that barrier=0

I am running Xen bundled by Debian - there are some discussions on the
internet about issues handling of barrier's by Xen.

I am already running EXT3 volumes, so I have added that option to see if it helps. Since I forgot to include in original post...
distro: Ubuntu LTS 64-bit
kernel: 3.2.0-31-generic #50
Xen package: xen-hypervisor-4.1-amd64         4.1.2-2ubuntu2.2

We'll see if I can go a week without corruption with the barrier=0 option. I looked into filing a bug per Fajar's suggestion, but I'm not sure how I'd go about gathering the data they want given the nature of Xen (gather data in DomU or Dom0? is gathering the data several hours after the corruption occurs acceptable since it's not always immediately apparent?).
