sudo lspci -vv output

On any kernel with this commit (commit 616d9cee4fdc4a377c03be8fd6efa5df4fcd0d81
Author: Chris Wilson <chris at chris-wilson.co.uk>  Date:   Fri Jun 16 15:05:21
2017 +0100 drm/i915: First try the previous execbuffer location), I get screen
corruption once X starts (text does not update, flickering).

I'm currently running Linux kernel 4.14.0 with this commit reverted and not
seeing the issue (which I'd determined by bisection between kernel versions
4.12.8 and 4.13.0).

I have attached my "lspci -vv" output. Feel free to contact me if you need more
information.
