[Linux] Dota crashing just after launch with Kernel 6.9rc5 about dota-2

[mfed3]

Confirmed seeing the same issue on Dota 2, both with the info in the gists and also after downgrading kernel to 6.6.30 still the same issue.
Operating System: NixOS 24.05

Kernel Version: 6.8.9 (64-bit)
Graphics Platform: Wayland
Processors: 32 × AMD Ryzen 9 5950X 16-Core Processor
Memory: 62.7 GiB of RAM
Graphics Processor: AMD Radeon RX 7900 XT

Kernel 6.9 was released it contains fix for this bug.
So people who are affected by this issue can update their systems to 6.9 stable or alternatively wait for fixes in current branches like 6.8.10 and 6.6.31 - which should appear this week.

I think we can close this topic to avoid spam.

Bug is created against kernel DRM, it is bisected. Please feel free to add comments here's https://gitlab.freedesktop.org/drm/amd/-/issues/3343

1. No
2. Kernel 6.8.9 and 6.6.30 LTS have the latest path-versions at the same time, they get the same change of amdgpu driver.

If you have "Above 4G decoding" in BIOS setting, enable it to resolve the issue. Or downgrade back to the previous path-version of the Kernel.

[Zesko]

1.then if its driver issue why most of people in gitlab talking about kernel version not mesa driver?

Yes, the bug is in the amdgpu driver in the current kernel, not in Mesa. Mesa is not a amdgpu driver itself, but an implementation of OpenGL, Vulkan and other graphics APIs.

[Thorinori]

Its mesa driver bug or kernel?

Kernels 6.8.9 and 6.6.30 have this bug. They should be fixed later.

Any idea when? Tried the Above 4G BIOS option and it worked once but then Dota just kept crashing still. Would ideally prefer to not have to roll back to an older kernel version, but definitely not a fan of the crashing.

I mean its not a solution

It's not. But it's not a Valve issue, it's a amdgpu bug which is tracked and being worked on. https://gitlab.freedesktop.org/drm/amd/-/issues/3343

And Alex pushed it into our internal branch, should be upstream by the end of the week.

The patch is here: https://patchwork.freedesktop.org/patch/593130/

Hello @AngryPenguinPL, libvulkan_radeon.so hints that this is a regression in your video driver. You should report this issue to your video driver vendor.

archlinux 6.8.9-arch1-1, dota crash after launch:
Process 6194 (dota2) of user 1000 dumped core.
Stack trace of thread 6260:

No problem on lts kernel

[koreanfan]

If you are lucky and dota dont crash immediately then go to video settings and set display mode to windowed and press apply. Kill dota or wait when dota crash. After that go to dota settings and delete all launch options. Launch dota. Seems no crash. If after those manipulation dota crash then try to kill dota and kill steam. Relaunch steam and launch dota, it should work but not stable. You can play demo mode and when quit dota and try to relaunch then dota may crash randomly. In replay mode dota crash. So i dont recommend to launch online match. So wait for fix from devels(mesa/valve).

Replying to #2694 (comment)

Me too...maybe they have some actual patches and applied to LTS kernel too?
I use 6.8.0 without any problem

[baaannnaaannn]

Replying to #2694 (comment)

Found a solution?

[baaannnaaannn]

To resolve the issue, downgrade to kernel 6.8.8.

Kernel 6.8.9 is an issue with the AMD GPU.

So its mesa driver bug or kernel?

1.Does mesa driver coming with kernel,including kernel?(im new to Linux sry idk)
2.how can this effect into LTS kernel?

[baaannnaaannn]

1. No

Again sry for this,I just want to understand

I just realized THANK YOU SO MUCH

[Zesko]

Any idea when?

Which distro do you use?

Did you enable "Resize bar" in the BIOS setting? If it does not help, there is something wrong with your system.

Or build your own kernel with some bugfix paths. If you don't want to build it, try the bleeding edge kernel 6.9rc7

EndeavourOS (Arch Based)

I don't recall seeing that, I did enable Above 4G though. Might have missed something though. I ended up just rolling back my kernel to 6.6.29 instead for now

[say8hi]

OS: Arch
WM: Hyprland
Kernel: 6.8.9-arch1-2
GPU: RX 6950 XT

Can downgrading amdgpu drivers help? And is it even possible?

[mfed3]

Honestly best thing to do is just enable Above 4G decoding in BIOS

[lewisdiamond]

I tried that with no success. Looks like rollback is necessary.

Worked for me, ty

Turns out CSM has to be disabled for Resize bar to work. With Above 4G decoding=enabled, Resize bar=auto and CSM=disabled the problem is fixed.

[bemug]

Enabled Above 4G decoding and Resizeable bar and everything is back to normal. Kernel 6.8.9-arch1-2. Thank you.

What if my motherboard doesn't support 4G decoding and resize bar but problems still here

I mean its not a solution
