--- Comment #12 from Chris Wilson <chris at chris-wilson.co.uk> ---
That basically depends on whether the failure pattern is universal (any gtt
write/read) like on gdg or specific to this test. At the present time, it is
quite clear that we have a number of errata with gdg's CPU that we are not
taking into account (that being adding noclflush fixed quite a few issues by
itself is telling). I don't think it is very likely that gm45 with a Core2 is
going to be exactly the same issues as a Pentium4.
