I've found NTPD to be rather fragile, and have used strace to chase down 
problems getting it to run.  

For example, on my box, /dev/gps0 is a symlink to /dev/ttyS0.  If ttyS0 
does not exit then ntpd will segfault on startup.  Running 
"strace /usr/sbin/ntpd -gn" then ends with:

readlink("/dev/gps0", "ttyS0", 80)      = 5
