Do you have any ideas how can it be debug more ?



decrease_reservation fails for one page when the page does not belong to the guest, or that the args passed to the decrease_reservation() are invalid (wrong order, wrong extent). Which is unlikely here.

Please try with rev 1.18 of xen/x86/xen_bus_dma.c; hopefully the error message will be more meaningful.
