Hi Hugh, Thank you very much for your very thoughtful input. I quiet positive this problem is PTI regression, because exactly the same problem I see with kernel 4.1 to which I back-ported all the necessary PTI patches from 4.4.110. I will provide this thread with more information as I

The hardware works :) I meant that before the patch linked in https://lkml.org/lkml/2018/1/5/534, I was never able to boot 4.4.110. But with that patch applied, I was able to boot it at least once, but it could be accidental. The hang/panic does not happen at the same time on every boot.
