--- Comment #3 from Chris Wilson <chris at chris-wilson.co.uk> ---
It appears that 5s after queuing the initial requests, we haven't even
submitted them to HW. Quite distressing!

I see you are running with tip, could you please enable
CONFIG_DRM_I915_TRACE_GEM=y and apply something like:

diff --git a/drivers/gpu/drm/i915/i915_gpu_error.c
b/drivers/gpu/drm/i915/i915_gpu_error.c
index df234dc23274..6207bc35a53d 100644

                return;
