We know that whenever a process needs i/o time it goes to block/wait state. At that time cpu is idle and it can run other processes. What happens during the deadlock ? In which state do the processes go, so that the cpu freezes ? If all the processes during deadlock, go into block state then why does the cpu freezes ? The cpu should stay idle, but it should not freeze . Can anyone clarify ?
