Thread-topic: [Xen-ia64-devel] Xen crash when creating VTI in some machines.
Hi Kan:
        <f000000007b30080> is an address belong to free_domheap_pages(). I 
found if reversed your patch, the issue will not meet. Could you give a review 
to your patch, maybe there is something lost. 

Good good study,day day up ! ^_^
