      Type:  defect           |     Status:  assigned
  Priority:  normal           |  Milestone:  6.1
 Component:  score            |    Version:  5
  Severity:  normal           |   Keywords:  SMP, qualification

------------------------------+--------------------------------
 The bug is related to this requirement: While the processor allocated to
 the thread is owned by a helping scheduler, while the processor is the
 only processor of the scheduler, when the processor is removed, the thread
 shall be blocked with respect to the scheduler. A test case for this
 requirement showed that a scheduler node change is incorrect in
 _Scheduler_SMP_Remove_processor().
