IF SRB #1 that is non-preemptable schedules SRB #2 and then does a PAUSE, SRB #2 can still be dispatched.
Sorry if I wasn't clear. SRB #1 can't be interrupted to dispatch other work on the processor it is running on, but that doesn't mean nothing else can run. Also, if it stops itself, the dispatcher is going to find something to dispatch on the processor. Once the event happens that will resume the paused SRB, it will be dispatched again and run until it is done or issues another PAUSE. Think about it. If you had a non-preemptable SRB running on a uni-processor, and it issued a PAUSE, and nothing else could run, how would the PAUSE be resolved?
