For some reason the BIOS is not reporting the other CPU. You could double check with acpidmp / iasl -d if that's what the BIOS really reports, but normally it should work. > [ 0.000000] SRAT: Node 0 PXM 0 0-e0000000 > [ 0.000000] SRAT: Node 0 PXM 0 100000000-220000000 > [ 0.000000] SRAT: Node 1 PXM 1 220000000-420000000 -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
