Search for “amdgpu ring gfx timeout”. There seem to be a whole class of bugs that have been open for years which not only haven’t been fixed, but there isn’t even any clear indication of what the root cause(s) is/are.
- talex5 6y agoI tried a couple of different AMD cards, and my machine crashes on resume if I try to use either of them (but the Intel iGPU works fine). Searching for amdgpu bug reports leads to: https://amdgpu-install.readthedocs.io/en/latest/install-bugrep.html https://amdgpu-install.readthedocs.io/en/latest/install-bugr... which links to a page saying "Bugzilla is no longer in use" :-( This is under Qubes/Xen, though, so maybe that causes extra problems. If any devs are reading, I did report it here in the end: https://github.com/QubesOS/qubes-issues/issues/5459 https://github.com/QubesOS/qubes-issues/issues/5459
- garaetjjte 6y agoIt could be misbehaved applications. While AMDGPU and Mesa are much faster than AMD proprietary driver (on some OpenGL workloads I have seen 2x improvement compared to AMDGPU-PRO or Windows driver) and are normally stable, I had several issues where bad shaders brought down whole GPU (with "ring gfx timeout"). Things like out-of-bounds access or division by zero.
