Pandaboard boot problems persist (was: [PATCH] Fixed unaligned access)

today I built the latest Barebox version for Pandaboard, which
includes the 'Fixed unaligned access' patch, but I still won't get it
to boot.

Maybe I'm missing some configurations that differ from the defaults,
anyone had success booting Barebox on the Pandaboard?

At power on I get the following message:

Is this error directly related to the current issues with Barebox on
the Pandaboard?
