System Information
Operating system: Windows-10-10.0.18362 64 Bits
Graphics card: AMD Radeon VII ATI Technologies Inc. 4.5.13558 Core Profile Context 26.20.11015.5009

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: f6cb5f5449
Worked: (optional)

Short description of error
When I try to render (in cycles) with a Volumetric Shader attached to a Cube and its hidden in Outliner, I get a System crash, even to this state, that i had to repair Windows (after 6 crashes till I found the cause)! I also get a PC crash, if I try to disconnect the volume scatter node, while in rendered view. When the volumetrics Object is visible, then it seems stable and renders fine.
I'm Pretty sure this is a AMD Driver / GPU related Problem, because when I render with the cpu, it works fine…
Apart from that, my system is rockstable and I had no crashes or bluescreens since I Bought it (6 months old)

Exact steps for others to reproduce the error
Open the atached file and go in the rendered view. But I think ist AMD/ Radeon GPU related so everyone with a nvidia GPU should have no Problems at all.

Can not reproduce crash.

@tibor81 Is this still an issue with latest build? https://builder.blender.org/download/

yes, it's still an issue! I've tried it right now and the example scene caused a displaydriver crash (amdkmdap) in cycles view, but not immediately. Fortunately my pc didn't crash at this time!

Do you have an AMD GPU?

Yes, I am running Radeon RX550.

I am re-testing your file again, and Blender freezes/crashes.
It also took down my sound card driver.

note: test with crash was done when PC was awaken from sleep. If I do restart I can move around in viewport for about 5 seconds, then it crashes

I have this same bug and Blender crashes when using GPU, I use Sapphire Radeon Nitro+ RX 590, but my AMD Ryzen 5 2600 CPU works. They probably won't fix this because mods keep closing it, it's been posted since 2019, and don't forget that Blender is free.
