With defconfig, and dts without a slightest change this
is still reproduceable (the logs I was posting to this thread
were done with _slightly_ modified config, and unmodified DT).

But... the board itself is modified. It is not a pure armada-xp-gp.
I still doubt that this crash is because of the board's mods, for
example please find the same crash here:
