A couple of questions:

        - Do you use PCI passthru? 
        - Is there something special happening when it freezes? 
        - Does it freeze at regular intervals, at the same time/uptime, or 
        - By freezing you mean it doesn't respond to anything? Or does it 
        - Can you try using the old kernel with the new xen hypervisor?

Try adding "loglvl=all guest_loglvl=all" for xen.gz.

And try adding "nomodeset" for dom0 kernel (vmlinuz).
