scrolling through from "dmesg -w". (And that is on a blank X11 display with just "xclock" and an idle "xterm".)
drm/ttm: fix incrementing the page pointer for huge pages
When we increment the counter we need to increment the pointer as well.
Try it on top of 5.2.
Even GPU reset fix coming soon (one patch was lost during older merge).
[PATCH 4/4] drm/amd/display: Restore deleted patch to resolve reset deadlock.

I hope that by version 5.2 the black screen flickering, that occurs during games in freesync mode on my Benq EX3203R Freesync 2 monitor, will be fixed.
