It appears there is some issue in the build environment on Fedora 19. It
could be compiler version also. Compiling cloned 3.14 on it works fine,
but then any change, even simple noinline of an existing function will
cause it to hang during boot, both in PV and PVH mode. 

   FC19: gcc (GCC) 4.8.2 20131212 (Red Hat 4.8.2-7)

I finally setup a mach environment with 6u5 and compiling there, everything
works fine: 

      gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)


JFYI.. watchout. 

So, finally, I've got everthing working, and will now get back to dom0
PVH patch..

thanks
Mukesh

I wonder if the issue you had been seeing was related to this compiler?
You might want to update your Fedora 19 to Fedora 20.
