Bug ID: 100995 Summary: System hang using OpenGL 4+ features Product: Mesa Version: 17.0 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: Paul.Hancock.17041993@live.com QA Contact: dri-devel@lists.freedesktop.org
This is easily reproducible via unigine's heaven benchmark, simply running it with normal tessellation settings results in the screen flashing black a few times and then an eventual system hang before anything even starts to render. A power cycle is the only way out.
Simply creating a 4.5 context will not trigger the bug, haven't been able to fully test what causes the hang specifically as accessible tools I've found are not compatible with mesa due to only creating a default context (which is currently 3.0), thus crashing on init.
