[ARM APM Mustang-X. Xen 4.5-rc1 and staging] Booting issues, last meesage: (XEN) P2M: 3 levels with order-1 root, VTCR 0x80033558

[Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>]

Hey,

I've been following: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/APMXGeneMustang#Preparing_all_the_Images
with a couple of changes:

1) The latest Linux tree in https://github.com/AppliedMicro/ENGLinuxLatest
looks to have already Xen support in the default config. So used that instead
of 3.15.


2). The 'run xen_run' does not execute properly, but if I run each
 operation by itself it does get me to boot Xen.


However I am not sure if the reason I am getting stuck is because I should be
using 3.15-rc8 instead of the latest? Or perhaps there is another issue?

And here is the serial console
