When a scheduler message starts porcessing,we start the scheduler watchdog timer, and in few cases when the system get under heavy load processing tasklets and bottom halves, and the scheduler message is preempted, its not getting a chance to run and the scheduler watchdog timer is triggered and it causes a panic. Since the scheduler watchdog timmer is less than the kernel RCU timer, were are having scenarios, where because of the scheduler watchdog panic, the RCU stall is masked. So in case of scheduler watchdog we wanted to just print the information about the message being processed by the scheduler and not panic.
