PPS is on DCD physically, I have checked it by scope many times, it is
enabled by the setting on the card and I think ntpd has nothing GPS card
setup. As I know well, it fetches the data coming through serial line,
nothing else.


But ntpd is exactly the same on both kernel, I patched and compiled it
when I compiled 2.6.15.7 and later I replaced the ntp binary on 2.6.24
(the old kernel runs on a FC5, while the new is on a FC6). And that common
ntpd binary works well with any other setup with both kernels. Thus I
thought, not ntpd is wrong, what it says is correct: it does not see PPS
on DCD pin.

That would be difficult, because Rockwell stopped producing his GPS chip,
I heard the license was sold to a Chinese company. But when it was in
production, there was no support for ntpd at all.
