I'd apprciate if you can build a working kernel with CONFIG_DEBUG_MEMORY_INIT=y and run it with memblock=debug mminit_loglevel=4 in the command line. If I understand correctly, DEBUG_LL is not an option for these platforms so if earlyprintk didn't display the log there is not much to do about it. > Thanks, > Guillaume -- Sincerely yours, Mike.
