Hello, @KMANO3​:


Thank you for contacting Intel Embedded Community.


Could you please clarify if this situation happens on your design or a third- party design? 


In case that it is a third-party device, could you please inform the name of the manufacturer, its model, the part number, and where its documentation is stated?


On the other hand, could you please let us know how many units of the project related to this circumstance have been manufactured? How many are affected? Could you please give the failure rate? Also, could you please list the sources that you have used to design it and if it has been verified by Intel?


Could you please give pictures of the top side markings of the affected processors? By the way, please provide the part number of the processors associated to this situation.


Finally, could you please explain the procedure that you have used to determine this condition?


We are waiting for your reply.
