Hi GreateWhite.DK,

Are you sure your kernel stops there? This function does a trap (system call "clone"), and you might not be able to step into it. Problem probably happens somewhere down the path of clone system call. My advice is put a break point at the entry of nios2_clone() and see what happens.
