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The "outdated DT detected, suspend/resume will NOT work" is due to the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.

I will try to reproduce it today and see what happens.

It seems that Osstest is using the device tree provided by the debian
installer.
I did try with the device tree provided by Linux and it boots without no
issue.
We may want to use the device tree attached to every Linux version in
order to avoid a such problem. Although, I don't much know

I gave a quick look to see what happens. pmu_base_addr is NULL because
it's initialized only when the PMU is an interrupt controller (see
exynos_pmu_irq_init). So the first pmu_*read* will segfault.
I suspect it's an unwanted behavior because the warning only says
suspend/resume won't work. Not the kernel will crash.
Although, we know that DT is often tight to the kernel version. So I'm
not sure if we should care of it.

Yes, we probably should update things to use the dtb from the kernel
build.

Right, I think this should probably also be fixed. It might be as simple
as turning the existing pr_warn into pr_warn+return?

I just sent a patch on the Linux ML to switch from pr_warn to
pr_warn+return.
