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.
