OK, stacktrace and code checks show clearly scratch[0] is null for ggtt
on gen < 6:
... ggtt_probe_hw(...)
{
...
if (GRAPHICS_VER(i915) >= 8)
ret = gen8_gmch_probe(ggtt);
else if (GRAPHICS_VER(i915) >= 6)
ret = gen6_gmch_probe(ggtt);
else
ret = intel_ggtt_gmch_probe(ggtt);
...
}
And setup_scratch_page for ggtt is called only from gen[68]_gmch_probe.
Anyway, speculative read is observed since gen12 anyway, so limiting to
gen12+ should be enough to avoid null scratch.

Andrzej
