I did include that possibility. But most NUMA systems I have set up myself will not boot if Socket 1 is full and Socket 0 is empty. The early boot code generally assumes Socket 0 is valid when first initting itself. > Also does the kernel have NUMA support enabled? Good question, the vast majority of standard SMP kernels do have NUMA at this point I believe. It would maybe be good to see if the issue went away if the machine was intentionally run with a UP kernel. > Long ago there was a bug in DPDK where it got NUMA socket info from > /proc/cpuinfo.
