When rendering on CPU+GPU, Blender throws an CL_INVALID_KERNEL_NAME
Exact steps for others to reproduce the error
Just render the file.

EDIT: This also seems to be a driver issue, I just uninstalled all the drivers for the GPUs, did two rounds of clean-ups using Guru3Ds DisplayDriverUninstaller and then reinstalled the latest driver version for the GPUs (19.6.2). Now it does render on 3GPUs quite stable, however when using the GPU connected to my monitors, after a short time the whole Screen turns black for a few seconds and when it shows my desktop again blender either has crashed or has turned into a white window. That also happens every time and is reproducable across different scenes. However in an older version of Blender 2.8 (prior to 2019-06-01) rendering on 4 GPUs has worked without any issues.

This black screen issue is common when using OpenCL.
You have to wait for all kernels to compile the first time it render (this may take about 1 minute).
Good to know that the reported issue has been fixed.
Closing.
