Thanks for the report. I think this is as likely to be a dom0/domU kernel
issue as a hypervisor one, but I'm not sure.

Would you mind reporting this to upstream per:
    http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen
please.

We could forward it but I expect there will need to be some back and forth
with the maintainers so it makes sense for you to speak to them directly.
You can CC 810964 at bugs.debian.org to keep this bug in the loop.

In addition to the information you provide here I would expect upstream to
want to see the full "xl dmesg" and "dmesg" from dom0 with and without Xen
and with 4.1.4 as well as something exhibiting the issue (4.6 is probably
best)

Thanks,
Ian.
