Bug ID: 108608 Summary: Blank screen after KMS with Linux 4.19.0 on Hawaii (R9 290) Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: abortretryfail@gmail.com

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.

--- Comment #1 from Alex Deucher alexdeucher@gmail.com --- Please attach your full dmesg output. Can you bisect?

--- Comment #2 from abortretryfail@gmail.com --- 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.

--- Comment #4 from Alex Deucher alexdeucher@gmail.com --- I think this patch should fix at least some of the issues: https://patchwork.freedesktop.org/patch/259364/

--- Comment #5 from abortretryfail@gmail.com --- 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.

--- Comment #7 from abortretryfail@gmail.com --- I guess we might as well close this out, since it sort of works now and the display corruption is a different issue.
