Please attach your full dmesg output. Can you bisect? Sure. I'll see if I can turn off all this 'audit' nonsense that's filling dmesg with the names of files and users on my PC that I don't want all over the internet. Haven't built a kernel from source in ages and never done a git bisect on one. I'll give it a try though. Created attachment 142312 [details]
Full dmesg output after crash
I think this patch should fix at least some of the issues: https://patchwork.freedesktop.org/patch/259364/ It works! Mostly. Everything seems to run fine until after a suspend/resume, after which i get scrambled gibberish on one monitor (DisplayPort-0) and nothing on the other two (DVI-D-0,1). xrandr --output DVI-D-0 --off --output DVI-D-1 --off gets things looking normal again on DisplayPort-0, but re-enabling either of those displays doesn't work and brings back the gibberish.

dmesg after suspend/resume
I guess we might as well close this out, since it sort of works now and the display corruption is a different issue. |

Created attachment 142294 [details] dmesg spew With radeon.cik_support=0 and amdgpu.cik_support=1, I get a blank screen on Linux 4.19.0. This worked fine on 4.18.16. Machine is still accessible via SSH, but will not shut down successfully. Using radeon instead of amdgpu is a work-around. By the function names I'm guessing it's UVD/PowerPlay related, but this is out of my realm of troubleshooting expertise. Attached dmesg snippet with traces and detailed error messages.
