All of CI is just failing with the following, which prevents loading of
the module:
i915 0000:03:00.0: [drm] *ERROR* Scratch setup failed
Best guess is that this comes from the pin_map() for the scratch page,
which does an i915_gem_object_wait_moving_fence() somewhere. It looks
like this now calls into dma_resv_wait_timeout() which can return the
remaining timeout, leading to the caller thinking this is an error.

shouldn't == 0 also be an error since it would be a timeout?
