> Which Git commit of Mesa are you using? Any local patches on top?

Every, since ever, as always (even, since _before_ Aug 22, 2018) ...;-)

But kidding aside, _currently_

#0ff1ccca25

(with merged branch from Marek for testing purposes)
04ba4eae68 (HEAD -> ext_gpu_shader4) Merge branch 'ext_gpu_shader4' of
git://people.freedesktop.org/~mareko/mesa into ext_gpu_shader4
0ff1ccca25 (origin/master, origin/HEAD, master) radv: call
nir_link_xfb_varyings()

Has it something to do with the DRM version?
DRM 3.26.0 (4.18) vs. DRM 3.27.0 (4.19)?

But this commit is _in_ since

and I had it running (on stable and amd-staging-drm-next, daily), even with AMD
testing code (Huang Rui ray.huang at amd.com), Aug 16, 2018.

Do you need more logs?
With which kernel parameter?
System _is_ running, but with unusable gfx/dri screen.
