Comment (by Stavros Passas):

 Hi Sebastian,
 Thanks for the suggestion; I ported over the failing test on a branch
 closer to head (I picked
 [https://github.com/RTEMS/rtems/commit/234d155e879d7ca72fa5dd9d29a8347fa294676e]
 as a reference point) and I cannot make the above testcase fail anymore --
 scheduling works as happens as expected.

 Could you point to some changes that might have changed the scheduler's
 behavior? I went through the commits touching directly EDF, and I didn't
 find any fix that could be fixing this.

 Thanks a lot,
    Stavros
