Volumetrics and simulations crash Blender 2.8.
Open, Waiting for Developer to ReproducePublic


System Information
Operating system: Linux-4.15.0-64-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.26

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: rBf6cb5f54494e
Worked: (optional)

Short description of error
Any kind of volumetric rendering, and on occasion some simulations, causes Blender to crash, it also crashes my OS as well and forces the computer to reboot. The daily build from 29/09/19 also crashes but not as often as the 2.8 version.
I have recently upgraded my computer hardware, I was not having any crashes before this upgrade. I have the latest available graphics driver and this has been reinstalled several times. The upgrade consisted of a AMD Ryzen 5 2600, a MSI X470 motherboard and 16 Gb of DDR4 RAM.

Exact steps for others to reproduce the error
Set up some volumetric rendering using the principle volume shader. Switch to the eevee render engine, set tile size to 8px or lower and the samples to 100 or greater.

No crashes here (even with 2px size and 200 samples).
Make sure you have installed the updated graphics card drivers.

System Information
Operating system: Windows-10-10.0.18941 64 Bits
Graphics card: Radeon (TM) RX 480 Graphics ATI Technologies Inc. 4.5.13570 Core Profile Context 19.7.2 26.20.13001.16003

Thanks for having a look at this it's much appreciated.

I have updated the driver to the 430.50, which the Nvidia website says is the latest one available for my graphics card, I installed it via a PPA, but I am still getting the same crashes when trying to use Volumetrics in the viewport or for rendering. The Blender crash still crashes my Linux Mint 19.2 OS at the same time.
I don't appear to have any overheating or lack of power issues and Blender is the only programme on my computer that crashes.

If you need any other info let me know.

EDIT: (wrong report)
In your case we need a developer who can reproduce the problem.
@Clément Foucault (fclem), @Jeroen Bakker (jbakker) can you try?

@Mark (caz747) Can you test with the 2.81 version (still in development)?

I have tested the test neb.blend file I uploaded to this thread with the 2.81 version and it still crashes on viewport rendering and after hitting F12 to render. If I change the tile size to 16px and the samples to 60 then the viewport renders and so does F12.
On higher samples and lower tile size the viewport will sometimes render but when I try to pan around the viewport by using the mouse middle button this will crash Blender after a short time, usually only a few seconds.
The 2.81 version I downloaded on 9/10/19.

As it seems difficult to reproduce this problem I do wonder if it might be something to do with my OS as this also crashes when Blender does. But I am not having any other crashes from my OS and the new hardware I added appears to be working fine.

Thanks for looking into this.
