I'm mainly using Debian compiled kernels. With 3.19.0-trunk-amd64, 4.0.0-1-amd64 and 4.0.0-2-amd64, I got dmesg output similar what is present in #89047.

It means that I must stick with the intel graphic card that cannot use DVI and HDMI outputs (or use the NVidia module) My laptop is an HP ZBook 15 with the latest available BIOS (L70 Ver. 01.32) Any ideas?
Same problem with my HP Zbook 15 G2. My Debian bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=789266
