Can you post the panic message, and eventually the stack trace ?

No, it's not the same problem. With Xen-2, all multiprocessor support is
in the Xen kernel, not in the dom0 kernel. The domain kernels don't even
know if they're on a multiprocessor or not.

Can you try without the flags ? It's possible that some special flags
triggers compilers bugs, optimisations issues or use some instructions
that are not handled by Xen.
