             Bug #: 2183
           Summary: Thread migration is broken on SMP
    Classification: Unclassified
           Product: RTEMS
           Version: 4.11
          Platform: All
        OS/Version: RTEMS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: cpukit
        AssignedTo: joel.sherrill at oarcorp.com
        ReportedBy: sebastian.huber at embedded-brains.de

See test case test_double_migration() in smptests/smpmigration02.

The Context_Control::is_executing indicator is insufficient to track double
thread migration requests.  It should be possible to replace it with a
generation count.
