This means that without interconnect drivers, the serial might not probe. Without serial console, the root might not be mounted by initramfs: + REASON=No init found. Try passing init= bootarg. PS1=(initramfs ... (initramfs) run-init -c /dev/console -n /root /sbin/init run-init: opening console: No such file or directory This means that interconnect drivers on these Qualcomm SoCs cannot be modules and must be built-in to mount rootfs.
