NTP issues with 5.4

[Michal Mertl]

Hello,

I run ntpd in daemon mode on several FreeBSD computers and synchronize
with 'ntpd -q' all others.

I've just updated one machine to 5.4 (from 5.3) and noticed the daemon
was unhappy, often logging 'time reset' and resynchronizing with peers.
On other machines I also only recently (after the upgrade to 5.4) see
ntp problems - 'ntpd -q' gets stuck and time goes off. The machines were
all fine before.

I searched the web and archives and found some more people complaining
about similar issues but I haven't found any good answer. At first I
thought it was happening only on SMP computers but it isn't the case.
The machines have all kinds of timecounters - ACPI-fast, ACPI-safe and
i8254.

Do you have any idea?
