[LinuxPPS] PPS stops working after a few seconds

[Heiko Gerstung]

Hi!

I lost my recent work on LinuxPPS stuff due to a hard disk failure (I 
know, I know, ....).

Now I am back on track trying to get the LinuxPPS stuff working again.  
I already build Folkerts ppsldisc version and tried to use it during my 
system startup, but it looks like the PPS stuff hangs after a while. I 
see that there is an entry in /sys/class/pps/pps0/assert but it does not 
increase anymore. It gets stuck around #36 and never goes up afterwards, 
no matter how often I kill ppsldisc and restart it.

The strange thing is that when I do not start ppsldisc during my system 
init phase, login to the unit afterwards and manuall kill ntpd, start 
ppsldisc and then restart ntpd, it seems to work.

My guess is that one of the other pieces of software that are running on 
my machine are doing something with the serial port that sends the PPS 
stuff into the bin.

Any ideas on what I could do besides starting this stuff manually?

Regards,
