Comments on The Model Checker SPIN by Holzmann

In this paper, we prove that there is an error in kernel scheduling which is proposed by Dr. Gerald J. Holzmann. We model the scheduling using ACST-VP and detect there is an error. Also, we check this fault using SPIN. We revise this scheduling and correct the error. And we verified that the fixed model is correct with the help of ACSR-VP and SPIN.
