  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.
