I have reproduced the problems Miroslav reports with the new startup
behavior on FreeBSD, indicating the problem is not isolated to Linux.
My guess is Solaris is the outlier here, because its adjtime() doesn't
enforce a 500 PPM cap. The system I'm using is psp-fb2, a FreeBSD 6.4
x86 machine with the latest ntp-dev snapshot which is known to
normally keep time well.
I ran several tests, but I think the last is the most interesting. I
stopped ntpd and removed its drift file (containing 80.530), then
slewed the time backward 100 msec using adjtime() and patience. After
restarting it takes a few minutes for its three manycast sources to be
found and sys.peer to be declared. Five minutes later, the frequency
is mis-estimated at 236 PPM, about 155 PPM too much. As a result, the
system sets up for quite a long settling period with many steps.
Below are the logs and some billboard snapshots. Please ignore the
refclock, it is marked noselect.
If your FreeBSD test machine has a negative ntp.drift, you might see
worse behavior with a positive initial offset. I am repeating the
test with the correct drift file in place now.
Cheers,
Dave Hart
