--- Comment #8 from Jari Tahvanainen <jari.tahvanainen at intel.com> ---
Assuming this to be resolved+fixed. If problem still persist with the latest
kernels (preferable drm-tip from git://anongit.freedesktop.org/git/drm-tip)
then please change status to REOPENED with the proper data included (see
https://01.org/linuxgraphics/documentation/how-report-bugs).

Side note: In addition to the diffs mentioned in comment 5, I also noticed that
connector DP-1/38 does not get connected on non-working case...
ON WORKING USE CASE
[drm:drm_setup_crtcs]
[drm:drm_enable_connectors] connector 33 enabled? no
--> [drm:drm_enable_connectors] connector 38 enabled? yes
[drm:intel_fb_initial_config] connector HDMI-A-1 not enabled, skipping
[drm:intel_fb_initial_config] looking for cmdline mode on connector DP-1
[drm:intel_fb_initial_config] looking for preferred mode on connector DP-1 0
[drm:intel_fb_initial_config] connector DP-1 on [CRTC:26:pipe A]: 1280x1024
[drm:drm_setup_crtcs] desired mode 1280x1024 set on crtc 26 (0,0)
ON NON-WORKING USE CASE
[drm:drm_setup_crtcs]
[drm:drm_enable_connectors] connector 33 enabled? no
--> [drm:drm_enable_connectors] connector 38 enabled? no
[drm:intel_fb_initial_config] connector HDMI-A-1 not enabled, skipping
[drm:intel_fb_initial_config] connector DP-1 not enabled, skipping
[drm:intel_fb_initial_config] Not using firmware configuration
[drm:drm_setup_crtcs] picking CRTCs for 8192x8192 config

Causing 8K resolution to be used on NON-WORKING CASE (?).
