Subjectnouveau "eDP-1: EDID is invalid" regression after 4.11 with HP ZBook 15 G3
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:

nouveau 0000:01:00.0: DRM: DDC responded, but no EDID for eDP-1
[drm] Cannot find any crtc or sizes - going 1024x768


$ lspci | grep NVIDIA
01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro
M2000M] (rev a2)

Any ideas, or should I bisect?
