This causes all standby memory configured for an LPAR to be used at IPL time. Note that this is definetaly not what a user wants on s390. The normal process is: define a certain amount of "base" memory which the system should use when IPL'ed, and define also a certain amount of "standby" memory which can be (also only partially) be additionaly used when necessary. Also note that it is *not* possible to add additional memory to a runnung system, besides the amount of memory specified as "standby". Therefore please change the kernel config option CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE to "n" for s390.
