This is the same problem as this post:
http://lists.xensource.com/archives/html/xen-devel/2010-06/msg01114.html

Stefano suggested I retry after Jeremy's pull.

Sync'd with 2.6.32.16 last night and it looks like the identical problem.

I can boot Ubuntu 10.04 with it's own native kernel, but not with a pv-ops kernel.

This is with # CONFIG_XEN_PLATFORM_PCI is not set, .config is attached.
