During the execution of a job, it may suspend itself, i.e., its computation ceases to process until certain activities are complete to be resumed. This paper provides a counterexample of the schedulability analysis by Devi in Euromicro Conference on Real-Time Systems (ECRTS) in 2003, which is the only existing suspension-aware analysis specialized for uniprocessor systems when preemptive earliest-deadline-first (EDF) is applied for scheduling dynamic selfsuspending tasks.
