It looks like you don't enable NAND (the GoFlex Net has NAND, isn't
it?). The problem is that the associated clock (runit) seems also to
be used for other purposes and the machine locks up when it is
disabled if neither NAND nor SPI are used. 

Thus, you either need to find Andrew's patch (can't lookup the URL
currently, the title is "Fix crash when neither NAND nor SPI") to
always enable the clock or you should add a nand part to your dts
file.

You can remove this. I think it is not used and it should be defined
in the dts anyway.
