Sorry for my noise!
My problem was NOT fast_page_copy related.
It was Justin's aic7xxx 6.1.12 release.
His latest 6.1.13 (2.4.4-ac6) fixed it for me.

My MSI MS-6167 (AMD Irongate C4) is running very well with APIC (it haven't
really have one) and ACPI (latest) enabled.

Below are some MMX copy results.

Thanks anyway.
Dieter

BTW Where can I grep the bench with MB/sec output?
