Hi, Reposting this to the xen-devel list after a suggestion by Boris Derzhavets. I'm trying to get Xen 4.0 going with a pvops-enabled kernel on an IBM x3500 7797 server. I've tried several different distros, including CentOS5.5, RHEL6 beta, FC12 and FC13. In each of them, I can run a Xenlinux (2.6.18) kernel, including the Xen-enabled distro kernels in CentOS 5.5 and FC12. However, if I try to run a pvops kernel, I get a panic. The CPUs are detected fine, but it seems to have trouble shortly thereafter. I can boot the pvops-enabled kernel directly and everything works fine. I only have trouble when booting it as a dom0. I've got two identical servers and it is a problem on both, so I don't think there's bad RAM. I also tried this with the latest 4.0-testing branch and had the same experience. Here's my console output from FC12 with a 2.6.32.15-compiled kernel. Please let me know what additional debugging info is needed.
