Would escalate to xen-devel and Yu Ke in particular.

Subject: [Xen-users] Xen 4.0 crashes with pvops kernel
To: xen-users@lists.xensource.com
Date: Monday, June 14, 2010, 12:55 PM
Hi,
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.
