After upgrading from 6.9.2 to 6.10.1 the system appears to make it through the boot procedure, resets, and boots again in an endless loop. I reimaged the USB to 6.9.2 and it boots to command prompt as expected. When on 6.10.X, I tried to boot into safe mode (with and without GUI) and experienced the same issue. My NAS consists of a FM2-A75IA-E53, A10-6700K and just two 8TB drives in RAID 1.
