System Information
Operating system: Linux-5.13.0-48-lowlatency-x86_64-with-glibc2.31 64 Bits
Graphics card: AMD Radeon RX 6800 XT (sienna_cichlid, LLVM 13.0.1, DRM 3.41, 5.13.0-48-lowlatency) AMD 4.6 (Core Profile) Mesa 22.0.0-devel
Blender Version
Broken: version: 3.2.0, branch: master, commit date: 2022-06-08 10:22, hash:
e05e1e3691
Worked: 3.1.2 (no GPU acceleration of course), no issue on 3.2.0 mac and windows
Short description of error
When importing an asset in a scene, with cycles / GPU enabled the system crashes after navigating a few times with MMB on viewport shading with GPU enabled (no issue on CPU)
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
Use the asset.blend file provided as an asset file, import the collection "Pixie_red", setup cycles with GPU enabled and try to navigate on the viewport shading with MMB. Then after a few tries (4-5 I think) the system freezes and display the ugly pixels as shown on the "crash.png" provided file. You can also use the provided blend file named "1.blend". With the same file on mac or windows plateform I have no issue. Everything is fine on Linux with CPU enabled instead of GPU.
As the system crashes I have no crash report.

Nobody has this issue ?
I tried the same process with another file (classroom from blender demo files), same problem. If I use blendluxcore render engine or radeon pro render render engine, everything goes fine.

Changed status from 'Needs Triage' to: 'Needs User Info'
Can you attach the crash log created by Blender when it crashes? https://docs.blender.org/manual/en/latest/troubleshooting/crash.html
Can you also attach your system info? Help > Save System Info.
Hello, I tried again this morning and made an append on all the objects of the BMW demo file, craash again. But the whole system freezes, no blender.crash.txt created in /tmp. I join you my system info. I join also another file made by "append" on the objects of the bmw demo file.
system-info.txt
bmw.blend
Oh, I thought only Blender crashed. So do you reboot your system after the crash?
If you reboot your system, can you attach the output of
journalctl -b -1
just after the reboot?If you don't reboot your system, can you attach the output of
sudo dmesg
after the system crashes?Yes I need to hard reset. For the crash related to the output you asked me for, here is what I did : on a new blend file with cycle GPU compute activated (32 max samples in viewport rendering, 250 for rendering, max bounce 6/3/3/4/0/3) , I append all the objects of the bmw demo file (on blender website) and navigate with MMB on viewport render on cycles. I join you the
And the bmw blend file I append the objects from.
There is no crash if I do a render (f12)

Looks like we are looking at a GPU reset in the kernel. So is not a bug in Blender itself. Can you try to update your kernel version and see if this fixes the issue?
Which version of the user space driver/ROCm are you using?
This comment was removed by @jean-martin-barbut
I was afraid it was the reason...
My kernel is the latest updated by the system : 5.13.0-51-lowlatency
As i'm using jackaudio a lot, I need lowlatency. I run ubuntustudio on KDE plasma (kubuntu).
I installed the rocm stack with this command :
I'm using those radeon repos :
Changed status from 'Needs User Info' to: 'Archived'
I see, your drivers seems to be up to date. I am not sure there is anything we can do from our end. I would suggest you try to report that to the AMDGPU DRM module in the Linux kernel.
Since this is not a bug in Blender itself, I will archive this for now and reopen later if needed.
By any chance do you know where to report to the AMDGPU DRM module in the Linux kernel ?
Create an issue here https://gitlab.freedesktop.org/drm/amd/-/issues.
Maybe check the README beforehand https://gitlab.freedesktop.org/drm/amd.
Thanks for the links.
I don't know if it is relevant or not but there is no issue if I use BlendLuxcore or RadeonProRrender render engine. It seems to be related with cycles GPU compute in viewport render.
BlendLuxcore and RadeonProRrender are built using a different technology, so it is expected that any issue that appears when using Blender may not necessarily appear when using either of them.
