Sorry you haven't had a response from us so far. This seems to be fairly clearly a Linux/Xen interaction and I don't know enough about Xen to suggest how to debug it. As it involves a relatively old kernel version, I don't think Linux upstream developers will want to hear about this unless you can also reproduce it with a more recent version. Linux 3.16 is available (in testing and wheezy-backports) if you would like to try that. I don't know whether the Xen upstream developers will accept a bug report against this version.
