Hi,
The HP ZBook 15 G3 laptop builtin display (eDP-1) does not work correctly with v4.11-11413-g2868b25.
When booting the laptop, the resolution seems to be limited to 1024x768, and gnome-session segfaults.
Up to 4.11 the display works just fine in 1920x1080 mode.
I'm seeing this in the kernel logs:

Any ideas, or should I bisect?

drm/nouveau/kms/nv50: use drm core i2c-over-aux algorithm
I'm not entirely sure NVKM needs to support this now, but I haven't removed it as of yet just in case it's needed from DEVINIT scripts where DRM isn't available.

Hi,
Hey Tommi,
Thanks for bisecting this. It's rather unexpected that you should be seeing problems here, but, the commit makes sense for it at least.
Are you able to get me new kernel logs of both before and after this patch with "log_buf_len=8M drm.debug=0x14 nouveau.debug=disp=trace,i2c=trace,bios=trace" please?
Thanks, Ben.
