So, assuming you haven't done this yet (sorry, I haven't checked), can
you report the details of the crash, and a summary of these findings of
yours, in an email to the xen-devel mailing-list?

I think, in this case, that's the proper place where to seek answers.

Since this is MM / P2M code, you may want to Cc people that takes care
of such code, i.e., probably, Jan Beulich, Andrew Cooper and George
Dunlap (for finding their email addresses, check the MAINTAINERS file
in Xen sources).
