I have added a eDP panel entry in the firefly reload board, once the kernel loaded analogix_dp-rockchip.ko, after printed the following two lines, the kernel stop working. rockchip-drm display-subsystem: bound ff940000.vop (ops vop_component_ops [rockchipdrm]) rockchip-drm display-subsystem: bound ff930000.vop (ops vop_component_ops [rockchipdrm]) In the early June of the 4.4 kernel, I meet the same problem with rk3288 evb board with different error message, I have to disable the display system that time. In the today test, I meet the same problem with rk3399 evb board in 4.4. I have no idea what caused that, and it is a little hard to debug as kernel still would never kill that task. Randy Li
