I am also having similar issues with xen-source-2.6.17 on my amd64 system. The system panics shortly after starting the xen kernel. unfortunatly, the system panics and reboots to quickly for me to gather any meaningful information. I will attempt to rememdy this and post further information. System mainboard is an MSI K8N Neo2 Platinum nForce3, cpu is an AMD Athlon64 3500+
