The Linux kernel panics for me between the second ([build] use-vbo=true) and third ([texture] texture-filter=nearest) benches of glmark2{,-es2}-wayland with Panfrost. Other programs I've tried such as es2gears and supertuxkart don't trigger this bug. Reproducing: 1) Launch weston with the Panfrost driver. 2) Start glmark2-wayland or glmark2-es2-wayland 3) Wait 20 seconds Actual results: Kernel panic. Expected Results: glmark2 displaying a textured cube.
