panic: unhandled exception
The behaviour is stable and reproducable on a Rock3A, probably also on other
boards. Maybe someone of the more experienced barebox devs already has an idea
what's going wrong here and wants to have a closer look, otherwise I'd probably
give it a shot within the next few days (and if I manage to find some spare
time...)
Best regards
Johannes
