[tech mind]

 Hi,

I am porting Linux on T4240 powerpc. The linux kernel hangs during intial
stage. Linux log messages are given below. What could be the problem for
the kernel to hang at this point.

Linux version 4.1.8-rt8+gbd51baf (root at esm-desktop) (gcc version 4.9.2
(GCC) ) #416 SMP Wed May 2 12:33:05 IST 2018
CoreNet Generic board
