This is a real failure (and I suspect the others are just things which
happened to run on arndale).

Tail of
http://logs.test-lab.xenproject.org/osstest/logs/55255/test-armhf-armhf-xl-arndale/serial-arndale-metrocentre.log is below.

The "outdated DT detected, suspend/resume will NOT work" is due to the
lack of an interrupt-controller property on the pmu device, which I fear
we may be suppressing somewhere while making the dom0 dtb.

The following null pointer exception I think is probably a bug arising
from trying to continue on regardless.

Ian.
