Yes, I am using my own config, It differs by compiling more stuff
directly in, some more modules, CONFIG_DYNAMIC_DEBUG is on. If I
understand the code correctly these messages just mean that there is no
omap4 cpu in the devicetree, so they are harmless.

shutdown -r 0  -> uboot menu -> choose another partition. -> kernel
hangs here often -> remove usb+ battery -> insert battery -> kernel
boots.

I have seen this behaviour also with letux_defconfig.
