[armv7] 13.1-BETA1-GENERICSD panic at boot on beaglebone enhanced

Hi all,

I'm getting the following panic at boot when trying to boot up the 
13.1-BETA1-arm-armv7-GENERICSD (from the FTP) image on a beaglebone 
enhanced (https://beagleboard.org/enhanced), which is "essentially" a 
beaglebone black (although I do understand that even minor variations 
may have a big effect on SoC): b

boot -v messages up until the panic are available at 
http://rionda.to/files/beagleboneenhanced-FBSD131BETA1-bootverbose.log 
):

This is the first time that I trying booting up FreeBSD on this board, 
so I don't know whether I need to do anything special.

Tomorrow I'll try to compile a -CURRENT image and boot it up, but if 
anyone has an idea of what is going on, please let me know.

Thanks,
Matteo
