Hi Kevin,

   This looks exactly like what I'm seeing except mine is an MCA.  It's
in the same area of xen bootup and the XIP of the MCA log is also
pointing at assign_domain_page called from dom_fw_dom0_passthrough.
Looks like Tetsu's patch provides a nice stack dump for helping to debug
this now.  Thanks,

        Alex
