- kernel 2.6.34 is running.
- pps-tools are compiled
- modules and line discipline loaded, /sys/class/pps/pps0 and /dev/pps0 found.
- ppstest is OK.
- ntpd is reconfigured with --enable-debugging, recompiled with new timepps.h.

As far as I can see ntpd has some problem. :-)
Yes, I suspect I have to discuss this on other forums.
Just tell me if have to to something with other softwares including kernel.

BTW. I wonder how can a PPS reference clock figure out the absolute time?
If I understand well, driver 22 listens only the DCD pin of
serial port but does not care what the GPS receiver says.
So it knows very accurate when the nex second starts but
it cannot know _which_ second is this.

Thanks for all the help. :-)
