I thought those extra options were just for NUMA systems and were about how the memory from several NUMA nodes "fits together" ie whether it has to form one continuos memory range or not. WRT to original question, I'd update BIOS and kernel to the latest version available and if that fails to rectifyy the problem, I'd try to toy with kernel memory option parameters
