             Bug #: 2124
           Summary: Strict order mutex introduces unbounded priority
    Classification: Unclassified
           Product: RTEMS
           Version: HEAD
          Platform: All
        OS/Version: RTEMS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: cpukit
        AssignedTo: joel.sherrill at oarcorp.com
        ReportedBy: gedare at rtems.org

The option to ENABLE_STRICT_ORDER_MUTEX is not implemented correctly. It can
introduce an unbounded priority inversion in certain circumstances. See
http://www.rtems.com/ml/rtems-users/2009/may/msg00093.html and the spsem02 test
case http://www.rtems.org/pipermail/rtems-devel/2013-May/003154.html
