Due to the use of an incorrect wait queue in the "dasd_sleep_on_immediatly" function, certain commands (for example, "tunedasd -S") used to stop responding, and system reboot was required in order to stop the running process. With this update, the wait queue has been changed to "generic_waitq", which resolved this issue.
An advisory has been issued which should help the problem
