The same layout as Jan Gregor showed is also on the M5.
Additionally, it seems the SD card is not being reset by BL2 (maybe not possible?) when the OS initiates a reboot. Then it doesn't find the SD card anymore and can't continue booting.
I tested SanDisk Ultra 128GB, Kingston 16 GB SDCA 10/16GB, Intenso Class 10 64 GB, all with the same problem.
