Are we to read this as "same kernels in DomU-s and Dom0"? If so,
that would hint at some subtle Xen regression. If not, you'd need
to be more precise as to what works and what doesn't, and would
possibly want to try intermediate versions to narrow when this
got introduced.

Yes, that indeed looks very similar. Nevertheless, without this
being generally reproducible, we'll have to rely on you doing
some analysis/debugging work on this.
