I have tried Xen 3.0.0 and 3.0.1 with 2.6.15 and 2.6.16rc1 from the hg
repository. The 2.6.16rc1 kernel crashes Xen itself. 2.6.15 gets much
further before dying. 2.6.12.6 boots fine.
Here's a boot log. I notice an invalid opcode ... do I need to use a
particular version of gcc? I can provide .config, syms, etc., if desired.
