Thanks for the report. I think this is as likely to be a dom0/domU kernel
(i.e. pciback/front) 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 810...@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 dom0 lspci for the devices you are passing through, as well
as dom0's /proc/interrupts and probably full "xl dmesg" and dmesg from both
dom0 and domU.
Thanks,
Ian.
