When I tesetd new firmware , which supports NUMA cpu/memory hot-add (with Windows), I found Linux/ia64 creates nodes with no cpus, no memory. This is because of acpi_numa_fixup(). It onlines nodes when they find pxms. Because SRAT can contain resources which doesn't exist at boot, the kernel can create a node with a empty pxm which includes not-exisitng cpus and not-exisitng memory. Now, I think this is a bug. These patches will fix it. These patches are against 2.6.16-mm1. --Kame - : send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
