Can you try to recompile your PVOPS kernel with CONFIG_DEBUG_PAGEALLOC=y?
You can read more about this BUG at
http://lists.xensource.com/archives/html/xen-devel/2011-03/msg01756.html
I initially hit this BUG sometime Dec 2010... ...
http://lists.xensource.com/archives/html/xen-devel/2010-12/msg01501.html
Thanks.
Kindest regards,
