Above happens if I select first listed device (Hawaii) only.
Benchmark 2.1 render if both devices are selected or second listed (gfx1010) only.
Other scenes render no matter which device is selected.

I think this is odd.

Does anybody have any idea?

The OpenCL drivers for 5700XT are broken, at the release they weren't able to render some of the LuxMark scenes too, do they all work for you ?

Adrenalin 2019 Edition 19.7.4 Optional from 29.07.2019.
All LuxMark 3.1 scenes work on both cards (one choosen only) with all openCL setting, benchmarks and VR (all openCL paths, all engines).

Try to disable OpenCL usage for film image pipeline, it looks like the place where it freezes for you :idea:

This is a good idea and I tested it. Tonemap openCL device disabled and first device (Hawaii) rendered successful. It also does if tonemap device was set to second openCL device (gfx1010).

I gave Photon GI a try but it did change the look of the render quite a lot. The floor bounce a lot more of warm light, which doesn't look bad, but what is more surprising is that the reflections are different? The bottom left corner where the wall meets the floor is very different.

However with Photon GI, Random sampler and noise threshold halt at 30, it rendered in 38.2 seconds, which is pretty amazing.

EDIT: Turning off the Automatic Lookup Radius and setting it to 50cm fixed the reflections.
