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:

$ lspci | grep NVIDIA

Any ideas, or should I bisect?

Hi,

Bisected this to:

commit df8dc97cd17269474344d73cc02739532c468d04
Author: Ben Skeggs <bskeggs@redhat.com>
Date:   Wed Mar 1 09:42:04 2017 +1000

   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.

dmesg after boot with drm.debug enabled:

v4.10-10409-g5c68d91 (still works):

v4.10-10410-gdf8dc97 (failure):

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.
