Does that make sense ?
It certainly may make sense, just that in what you have written so far I don't think I've been able to spot any evidence thereof. Since, as you say, nothing interesting gets logged by Xen, you must be drawing this conclusion from something (or else you wouldn't say "doesn't fix the issue").
