I just wanted to clarify that this is not limited to vertex colors. Thanks to a recently added feature, custom attributes created in geometry nodes can be used directly in Cycles without the need for vertex colors: https://developer.blender.org/rB3a6d6299d
Maybe the fix will apply to GN as well, but I think it would be good if you could modify the name or description of this task to indicate that it also affects geometry nodes, since you closed my task.

Tamás Péter Radványi (RTamaasP) added a comment to T71258: Viewport rendered preview freezes when using OpenCL on GPU.

@Tamás Péter Radványi (RTamaasP) This is not a place to talk about third party software. The OP (and so Am I) are on Linux. I'm aware about the eternal warning that substance painter gives you when you start it but it not applies to this issue. Furthermore, ATM I'm stuck with no GPU at all at 2.92. You can check that here. As I said, third party addons will not help to solve a bug.

So, for what it's worth, I changed this line: https://git.blender.org/gitweb/gitweb.cgi/blender.git/blob/HEAD:/intern/cycles/render/osl.cpp#l171

Using Radeon Software 20.10.1, with MSI rx580 8 gb OC ed. and doesn't work with ANY versions of blender, EXCEPT 2.92, but now it works extremely well. Like before this took literally minutes even to react anything after I applied the volume (and then crashed at 1 samples), now not even increasing the viewport render time.

Unfortunately, this did not work for me either. I also tried Blender 2.93, the same error occured. I use 2 Radeon RX 580 GPUs and the dirver version is 21.3.1. The same thing is with 21.Q1.1 Pro drivers.
