Hi.
Maybe I understand the cause.
It's side effect of CONFIG_VIRTUAL_FRAME_TABLE.
If CONFIG_VIRTUAL_FRAME_TABLE is defined, there is no page_info's
corresponding to ACPI table pages.
Thus set_gpfn_from_mfn() in assign_domain_page() causes dtlb fault
and xen dtlb miss handler falls to frame_table_fault and then
dispatch_to_fault_handler().
This is fixed by the patch balloon_driver_xen.patch
which I will post soon.
BTW
ia64_fault()
case 4:
printk("Alt ITLB.\n");
break;
Should This be "Alt DTLB"?
Thanks.

Have to say it's bad news. When I turned on
xen_ia64_dom0_virtual_physical in xen, it halts even before starting
dom0. Based on tip (Rev 9992). Maybe we should try this feature later

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
