Hmm, very strange, no sizes reported. Why is it using SMP and not NUMA for memory sharing? Is there a NUMA version of the 193 kernel I could use?
The kernel is NUMA. It cannot access the northbridge of the second CPU, so NUMA support is turned off. That's some hardware problem at your side, maybe the second CPU or the motherboard are broken or not correctly plugged in. -Andi
