Description ixn 2019-09-18 01:34:39 UTC
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.

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.

Build Date & Hardware:

Kernel: 5.3.0
Distro: Arch Linux ARM
Mesa: git master (built 2019-09-16)
Weston: 6.0.1
glmark2: git master
libdrm: 2.4.99
SOC: RK3288
GPU: Mali t760
