In addition to the kernel logging of the error I get this from the

Adding a bit more logging to the kernel I get:
gnttb_copy_grant_page old c22ebcd8 P:0x1ec8e M:0xc499d F:0x41000000
gnttb_copy_grant_page new c2324ce0 P:0x1fe18 M:0x11cd32 F:0x40000000

Notice how MFN 0x11cd32 has become 0x1cd32 by the time it gets to the
hypervisor!
