Thanks for the detailed report.  Would you mind re-posting this to the
xen-users mailing list?

Realistically though, at the moment I don't have the bandwidth to
maintain more than one kernel package for CentOS; so if you can
trigger it reliably, my only advice (other than backporting a patch if
one is available) would be to try it again with the 3.18 kernel
currently in the tree.  If it still faults there I can pursue
backporting a patch there.
