I found few more things: Once its stuck I can see CPU spining on exception 800 (Floating Point Unavailable) which calls load_up_fpu. Then load_up_fpu in turn enables FPU bit in msr and executes lfd fr0,THREAD_FPSCR-4(r5) which in turns generates trap 800 and again calls load_up_fpu. So I am spining in those 2 functions. Any idea how to approach finding what is causing it. According to MontaVista manual thing should just boot up.
