What > do I have to do to enable that interface? That interface depends on CONFIG_MEMORY_HOTPLUG. But given to that dependency list, 128 config MEMORY_HOTPLUG 129 bool "Allow for memory hot-add" 130 depends on SPARSEMEM || X86_64_ACPI_NUMA 131 depends on HOTPLUG && !HIBERNATION && ARCH_ENABLE_MEMORY_HOTPLUG 132 depends on (IA64 || X86 || PPC64 || SUPERH || S390) that interface is off on *many* systems (i386, x86_64), so we can't rely on that interface in kexec. I think on POWER it's much more common than on PC architectures. Bernhard -- Bernhard Walle, SUSE LINUX Products GmbH, Architecture Development
