Due to a bug in some firmware versions, Store Data requests might not get an event response in certain situations. As a result, the boot process will be blocked indefinitely. Fix this by introducing timeout handling for Store Data requests. In case a timeout occurs, the Store Data operation is halted and no data is retrieved from the SCLP facility. Note: A minority of installed systems rely on Store Data result for device auto-configuration. These systems will fail to boot in case of a Store Data timeout and will need to be switched to manual device configuration as workaround.
