I can skip the ExitBootServices call and keep printing, I have already
done thatn at least in C functions. I have no experience of doing that
from assembly code.

The same bug exists with a XEN3_DOM0 kernel. Xen starts up, and the 
kernel crash without displaying anything. I wonder if there are tools
to trace the dom0 with help from Xen.
