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

But after implementing the hypercall in the hypervisor(Cset#20339), both dom0 and hypervisor all performs correpsonding actions in this case, so issues happen. That is to say, if disable this hypercall either in hypervisor or in dom0, it should work, but if enable both, the issue occurs. So it should be caused by incorrect hypercall implementation Xiantao _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

We meet the dom0 crash on both Core 2 Duo and Xeon X5300 Serial platorm.
