The great thing is now I got the Xen console working, so can get the debug output. However the bounce buffer/hypercall issue i would think is far more important than MSI interrupts at the monument. Glad to know you got it working at the end! I've already pointed this out in my last email, but did you try to increase vm.max_wired even further? This usually happens when mlock in freebsd_privcmd_alloc_hypercall_buffer (xc_freebsd_osdep.c) fails to wire down the memory that would be used by the hypercalls. Roger.
