It turns out that is NOT the initial problem - I had missed the 'NTP
PPS support on serial port' option in the kernel config :-(

Recompiled / rebooted, now seeing PPS API message on serial driver at
bootup, but ....

Now ntpd dies at startup (bangs head on desk)

ntp.log shows -
29 Jan 23:20:46 ntpd[17128]: system event 'event_restart' (0x01)
status 'sync_alarm, sync_unspec, 1 event, event_unspec' (0xc010)
29 Jan 23:20:46 ntpd[17128]: ntpd exiting on signal 2

daemon.log shows -
ntpd[17128]: ntpd 4.2.0 at 1.1161-r Sat Jan 29 23:19:54 GMT 2005 (5)
ntpd[17128]: signal_no_reset: signal 13 had flags 4000000
ntpd[17128]: precision = 1.000 usec
ntpd[17128]: no IPv6 interfaces found
ntpd[17128]: kernel time sync status 2040
ntpd[17128]: frequency initialized 88.671 PPM from /etc/ntp/driftfile

(it does not even get as far as reading the peers in the config file)

I have even done a full re-compile/install of ntp, but this does not
help.

Has anyone any idea where to look next?
(it looks like I am about to drop out of ntp pool)
