They should return their preproduction icl in exchange for a production model.
Comment 7 Lakshmi 2019-07-16 08:36:50 UTC 
Adding comments from  Kumar Valsan, Prathap:

This is not actual BUG and expected on this stepping.  We need to run this test with on machines that is not PPOR:POR_M1.

Closing this bug as NOTABUG.
