Kernel: build initramfs vs squashfs

I've got a new ramips device initramfs-kernel.bin which tftp boots perfectly, supports all the hardware and everything works as I've tested. As soon as I tftp boot the initramfs-kernel.bin image, the kernel prints out usual info. But when I choose to build the squashfs-factory.bin in make menuconfig (and leave all other things equal, and update the kernel commandline in the DTS file) - and I tftp boot it, it just sits there. No kernel output... more than

Starting kernel ...


What could be wrong?

I'm just putting for newbies. Please glance this
