Yeah, let's just close this. Someone will re-open/file a new bug if it's still
an issue.

Presumed to be fixed by:

    drm/i915: Get panel_type from OpRegion panel details

--- Comment #20 from freedesktop at zevv.nl ---
Hi,

Reopening: I've run into this same issue on a HP ProOne 400 G1, and I've not
been able to fix or workaround with the info in this thread. 

What I have tried:

- Default install Ubuntu 16.04: halfway kernel boot console text disappears,
display goes into flashing color test pattern. Adding 'nomodeswitch' to kernel
parameters allows console to be usable.

- Tried the workaround from http://paste.debian.net/410285/, no changes

- Built 4.8.0-rc4 from scratch, still the same issue.

Let me know what info would be helpful here for further debugging. Can provide
SSH access to anyone who might be interested in examining the system.

Thank you,
