I see above errors even on my Vexpress TC2, but

.. not theses ones

Do you have an idea what might go wrong?


I will give it a spin on my CA9 coretile.

I'm testing on qemu (and not even the latest one), so this might be a
reason.

OK, I tried on my CA9 coretile and don't see these errors on it either.
However the "... creating of_node link" is present on both and I will
look at that issue.

Sudeep
