I'm sorry, are you saying there's an ldattach issue beyond the suggested 
patch on the install/setup wiki? I'm running a -patched- ldattach, though 
I've tried with an unpatched ldattach and gotten equally nowhere. Getting 
the ATOM refclock to work with LinuxPPS -is- possible, right? So I'd like 
to make it work, too :D

I tried running ppsldisc and ntpd and nothing really changed. I got 
positive system messages and my signal shows up in ntpq, but again, it 
never gets polled...

Cheers,

-kevin
