dri-driver via LLVM is a hack on top of a hack on top of a hack as the
developer of the software will tell you. It works in the use cases he
develops for but outside of that you are very much all alone. So even
trying to have a 'known' good is hard for this because what worked on
your laptop/system may not work at all on any other one.

Heck it might not even work when the Windows OS underneath does an
update even though the hardware worked. To quote the road sign

Expect problems. Road construction ahead.

If you are needing better stability then you need to staff up
somewhere to have people to fix those problems.
