on bug 99130
from Chris Wilson
Looks like the timeout value isn't being computed properly (possibly just that
too much time is unaccounted?). Can you apply:
diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c
index 1b2f18d0ca2b..dfe751b350ad 100644

}
and get the output for a failure?
