GPU Hangs When Performing Various Rendering (3D specific?)
Across multiple distributions, I have had issues with i915. I have experienced GPU hangs in multiple programs. The one that I encounter most frequently is with Firefox, but I haven't been able to notice a significant pattern with it. Sometimes when I open a website that seems to perform more heavy rendering, the GPU hangs. Sometimes it can recover itself (likely hanging again shortly thereafter), while other times I must switch to another tty and kill Xorg. When I get hangs with Firefox, the program reported by i915 in the kernel logs is Xorg. However, I have been able to consistently get GPU hangs while launching stellarium. I suspect that the same would hold true for other significant 3D rendering, but I don't have many programs to test that with. When I get a hang in stellarium, i915 reports that it was in stellarium, not Xorg. I have attached such an error, while running a drm-tip kernel. I'd be happy to perform any additional tests that might be useful, or provide more detail. Thanks.
