Ok, here is the version I have compiled and used this afternoon for testing with the scope:

http://download.goldelico.com/letux-kernel/stable-lx16/
(see also http://download.goldelico.com/letux-kernel/?C=M;O=D for updates)

This is what I get as boot log:

this differs from your

>>> [    0.000000] Kernel sections are not in the memory maps

Which might indicate a device tree install issue.
