With which .config is it happening? In my testing, the undefined CRCs show up as 0x00000000 in Module.symvers and they are also 0 in the ___kcrctab* sections in vmlinux. So the loader matches the requested and provided symbol's CRC of 0 and is happy. But I guess I'm missing something. Thanks, Michal
