You missed to attach failed dmesg while the system booted and aborted. Nevertheless, I expect problem with your defconfig, which does NOT have options set for initramfs. These ones: https://github.com/ZoranStojsavljevic/bbb-yocto/blob/master/custom/config-initramfs Please, could you add these one to your current .config, this might very well solve your problem.
