Hi Graeme,
We'll start with the basics. Can you add this to the kernel command line and send the output? I want to make sure the ACPI region is getting properly protected by the kernel:
memblock=debug

Arnd, Grant, Nico,
I am fwd'ing the message here below to your attention, as you are the most skilled problem hunters at Linaro :-)
Any suggestion for Graeme?
Thanks a lot in advance for any idea!

Hi,
I am going to have to admit defeat on this issue, I'm pretty sure its a lowlevel MMU/VM/RAM allocation/access thingy. But I know very little about the area.
Who can we call to give advice?

Hi,
I have managed to boot our ACPI enabled kernel on the beaglebone device which
has working earlyprintk.
You will see from the log below there is a very familiar looking RCU stall,
same place as I was seeing with Hanjun's patches. I did not check the size
of his blob but I suspect its the same issue and actually not to do with
cpu topology at all.
Anyway below is the log of the ACPI kernel booting on the beaglebone.
Thanks
Graeme
