It is good to know the Sagrad SDD file is disabling PTA in the
hardware even though there is a PTA record present.

Although, at least with the driver Dmitry posted on this mailing list,
the driver is taking action simply on the presence of the PTA record.
I can easily disable this for my testing.

I wonder if the parsing of the SDD file in the driver could be a
little smarter to detect that the PTA record is actually disabling PTA
and not assume the existence of a PTA record means PTA is being used.
