Chris Wilson f7096d40ee drm/i915: Sleep and retry a GPU reset if at first we don't succeed ... As we declare the GPU wedged if the reset fails, such a failure is quite terminal. Before taking that drastic action, let's sleep first and try active, in the hope that the hardware has quietened down and is then able to reset. After a few such attempts, it is fair to say that the HW is truly wedged. v2: Always print the failure message now, we precheck whether resets are disabled.
