Hi,

During earlier testst I used on dom0 xen/stable and on domU 2.6.32.9
from debian testing.

Then I switched to xen/next on dom0 and domU. And now I have new problem :)

Here is the full log from the boot: http://pastebin.com/e8hUeQUs
I'm still getting:
(XEN) mm.c:859:d0 Error getting mfn 40100 (pfn 5555555555555555) from
L1 entry 8000000040100473 for l1e_owner=0, pg_owner=32753

Now there are two ways:

FIRST:
as you sugested I tried pass-through another device (usb controller)

I added it to pci-stub:
root@debian:~# echo "8086 3a67" > /sys/bus/pci/drivers/pci-stub/new_id
root@debian:~# echo
"0000:00:1a.0">/sys/bus/pci/devices/0000:00:1a.0/driver/unbind
root@debian:~# echo "0000:00:1a.0">/sys/bus/pci/drivers/pci-stub/bind
root@debian:~# echo "8086 3a68" > /sys/bus/pci/drivers/pci-stub/new_id
root@debian:~# echo
"0000:00:1a.1">/sys/bus/pci/devices/0000:00:1a.1/driver/unbind
root@debian:~# echo "0000:00:1a.1">/sys/bus/pci/drivers/pci-stub/bind

on console i got:

[  253.516238] uhci_hcd 0000:00:1a.0: remove, state 4
[  253.518622] usb usb3: USB disconnect, address 1

[  339.692207] pci-stub 0000:00:1a.1: claimed by stub


Then I launched guest and it worked, guest could see usb controller. I
disabled guest, enabled it again, disabled it again and enabled it
again and got call trace:
