Sure, please see the attached log file. Please note that this dmesg data
comes from a system that I have booted from the standard XEN 4.2.2
kernel (i.e. w/o the WARN() statement and the various printk statements
I have added; furthermore this was w/o the serial console being active)

I'll get back to you in due course with the log output after I have
applied the patch and restarted & then shutdown XEN again.
