I am not an expert, but I am quite sure shaders have a big part in this. If you
can, disable shader caching.
There are a few tests you can do:
1. Did you try with the kernel parameters I posted above? I always ran all the
parameters together. GPU+CPU and at the time, I did not have crashes for weeks
on my Vega64. I am using a RadeonVII now and it seems those parameters are not
needed.
2. Valve sponsored an interesting project that removes dependency of AMD Mesa
from LLVM. And instead uses ACO. Valve made this available for Arch based
systems via AUR, and Ubuntu based system via PPA. If you want to test it, you
can check the posts below. I am going to test this myself on both Arch and
Ubuntu.
