Any chance you can grab the latest SLES 12 kernel and run it with pti and efi enabled to see if that works properly for you or not? I trust SUSE's testing of their kernel, and odds are I'm just missing one of their many other patches they have in their tree for other issues that they have seen in the past. If you want, I can just send you the full patch that they run on top of the latest 4.4 stable tree, so you don't have to dig it out of their git repo if you can't find the binary image. thanks, greg k-h
