Local fix
Problem summary
Machine crash and in KDB.
Problem conclusion
we are cancelling the timer request but we are not checking the return code as opposed to taking the approrpiate action in case of failure.Moreover as we are using the lock, lock shoul d be released ,a delay should be added and then the lock shoul d be reacquired .In a multiprocessor environment, the timer function associated with a timer request block may be active on another processor when the tstop kernel service is called. In case, the timer request cannot be canceled,A multiprocessor -safe driver must therefore check the return code and take appropriate action if the cancel request failed.
Temporary fix
