hm. sounds weird. Are you sure that you have the DTB appended to your

With device-tree, you don't have to worry with your machine number.

It depends on what your boot media is. For instance if you boot your
kernel and the rootfs on usb and necessary modules built-in you can boot
directly with things like root=/dev/sdaX rootwait.

either you use ARM_ATAG_DTB_COMPAT and set the command line on from
uboot or you don't set it and set the command line from the dts file.
