Thanks for the bisection.
Would you mind posting a full dmesg log for your 4.18.8 kernel?

done. Dunno if that's what you asked for, I am just a newbie...
I did start bisecting the second issue as well, but my free time is limited. I
think I'll finish this weekend though.
May I hope to get things fixed in a few weeks?

The log you posted should be sufficient. I'm not sure about a timeline for a
fix, however.

Couldn't you just reverse the commits ?
I did complete the bisection btw:
691f2d763d0731224439686ecf2d440df8fe910e is the first bad commit
commit 691f2d763d0731224439686ecf2d440df8fe910e
Author: Mikita Lipski <mikita.lipski@amd.com>
Date: Fri Jul 13 09:07:35 2018 -0400
drm/amd/display: update clk for various HDMI color depths
commit 81aca8e75c1b046865fb2badef95a0dcff6f73de upstream.
[why]
When programming tonga's connector's backend we didn't take
in account that HDMI's colour depth might be more than 8bpc
therefore we need to add a switch statement that would adjust
the pixel clock accordingly.
[how]
Add a switch statement updating clock by its appropriate
coefficient.

Does applying this patch help?
Try this on top of the tree without reverting the other patches.

The patchset from:
