Description
Created attachment 145346 Amber test that exposes the problem
Doing:
amber -d killer.amber
causes my machine to lock up (the display freezes, then goes into a pretty cool and crazy scramble of colours).
Build: Mesa 19.2.0-devel (git-2eace10c) (Debug) Device: Radeon RX Vega
I expect this is related to https://bugs.freedesktop.org/show_bug.cgi?id=111147 - that was a highly reduced shader. I have included the unreduced shader in the hope that the issue is less likely to be sensitive to small changes in shader compilation.
I have tried enabling amdgpu.gpu_recovery=1 but this doesn't seem to help.
