[LinuxPPS] Kernel configuration and more ......

[Paul]

First of all I compiled with the debugging messages. I got 4 events per
second to the screen (this is why I need to know if debugging is for the
PPS and/or GPS NMEA data).

I compiled exactly the same with no debugging.
The /sys/class/pps/pps0/{assert/clear} remain at 0.000
I checked the voltages on the serial plug and I saw the PPS pulses on
the DCD pin. I checked with statserial (which actually looks at voltages
on the serial pins) just to be sure I did not have a hardware problem.
