    Ha! I'd love to but the Manjaro developers don't care, or at least have never acknowledged any of the bug reports I took the time to make, and the upstream developers on Bugzilla just get mad and yell at you if you file a bug about Manjaro.

    But if someone knows where I can file a bug report that someone will actually consider, I'll take the time to file one again. The error is pretty obvious, and right at the beginning of boot so there's not even a journalctl log, just a brief Xorg log. It begins with "/dev/dri/card0: failed to set DRM interface version 1.4: Permission denied"

    And by the way I'm used to fixing things myself and took all the PCI cards out of my system, tried different slots, and different GPUs, etc. Everything works fine except my R9 390 with amdgpu enabled. I of course also looked for similar errors, and they were sometimes caused by libdrm so I tried compiling it from git but everything failed exactly the same way. So it looks like something in the kernel is hosing things up.

    If I have time later I'll try amdgpu-pro but I've never gotten it to work on Manjaro, so I don't have a lot of hope that will help.

    Another user was having the issue as well but they had a Vega 56. I'm currently on 4.18.18 (until 4.20 is released) for this exact reason.

    Thanks for the tip, I will decide if I leave the 120hz is just 24 hz less, but as you tested and found that you are gpu reset anway with that kernel (4.20) not need to upgrade for the issue with the 144hz, so the best will downgrade the kernel and wait for 4.20 officially release on arch. Thanks again for the tip.

I played rocket league but the hang occurs when I' m playing wihtout can be in 10 min, 20 or more same reason as Dota 2. Now with the update of the kernel 4.19 on arch I have some screen issues at 144hz, so i must set the monitor to 120hz, to avoid those problems.

    I can't say for certain, but I've set everything in BIOS to stock defaults just to isolate from any CPU overclocking, etc.

    I have the MSI Gaming X RX 480 8GB that has default clocks of 1303/2000 so I leave it at that for gaming with fans on auto. The temperature never gets too high, though.



    I hear you, man. It's starting to give me unnecessary anxiety because I know that GPU hang is coming for me, it's just a matter of when. Seems to happen at a crucial times too, right before an auto-save checkpoint or last few seconds of a Rocket League multiplayer match.

    I don't know for sure. I was under the assumption "requested VRAM" was how much the game asked for, and "VRAM usage" was total used by the GPU, including for other things, so in this case:

    948MB - Metro 2033 Redux
    227MB - Other
    ------
    1.175 GB total

    - CPU loads were 71, 57, 50, 75
    - FPS was at 163
    - VRAM usage was reasonable at 1.175GB

    So the GPU load at 99 is the only thing that sticks out here. Also, you'll also see on the bottom left the textures became screwed up. Usually when that happens, about 1 or 2 seconds later the hang happens, as the case here.
    I don't game nowadays, but looking into the picture..
    You have:
    Requested Vram 948 MB
    Used Vram 1175 MB

    Shouldn't it be:
    Requested VRAM >= 1175 MB?

    It's nice to see so much work put into AMD drivers, especially the compute unifying part. It would be nice to install one open-source driver and just "magically" get it all. Still waiting for my compute-graphics nirvana...
