I've now seen hangs also with drm-tip v4.20.0-rc3 kernel.
However, these GPU hangs don't happen anymore with this or later Mesa commit
(regardless of whether they're with v1.19 or v4.20-rc4 drm-tip kernels):
3c96a1e3a97ba 2018-11-26 08-29-39: radv: Fix opaque metadata descriptor last
layer
-> FIXED?
(I'm lacking data for several previous days, so I can't give an exact time when
those hangs stopped.)
Raytracing demo SPIR-V warnings happen still, although I updated Sacha Willem's
demos to latest Git version.</pre>
