The issue is also present on KabyLake Dell XPS15 9560 with i7-7700HQ with NVidia GTX1050M. It manifests itself with complete freezes if the intel card is used for X and the NVidia card is disabled with bumblebee. Then, running nvidia-smi, lspci casuses freeze. The freezes do not happen if NVidia card is enabled using bbswitch.
