They fail to initialize as the reset flow doesn't complete,  plainly it won't work. 

Similar patch has to be send for  3.7 and 3.8. It  Just needs to be done differently as there
was large code movement included in  3.9. 

I've assumed at the time that Lynx Point LP behaves same as Lynx Point but I was wrong.

Tomas
Thanks
