Re[2]: [Xen-devel] pv_ops DomU boot problem using pvgrub, xen 3

Hello Jeremy,

Let's give some more info:
Xen: 3.4.1-rc7 (xm info attached)
Dom0 kernel: 2.6.26-2-xen-amd64 (standard debian xenified kernel)
DomU kernel: self compiled vanilla 2.6.30.1 kernel with pv_ops stuff enabled

I am trying to boot a PV domain with PVgrub, config attached

Hmm could it be related to the topic: "[Xen-devel] Re: [PATCH] x86: detect
use of extended APIC ID for AMD CPUs" ?

gdb returns:
0xffffffff813ce1df <read_pci_config+43>:        out    %eax,(%dx)
