<pre>commit f7096d40eea84d32eb1e3b0f2b4407167aae9a83

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.
