[Xen-devel] Latest Pv_ops dom0 fails to boot

["Xu, Jiajun" <jiajun.xu@xxxxxxxxx>]

Hi,
I found latest pv_ops dom0, commit 3dd81018a392941fcc722ee521de344527481eb8,  
fails to boot with call trace. And commit 
34ffcd2bde0018cf78d5b4f1f5427c38a3e9b502 has no such issue. Could anyone help 
on this issue?
