I'm running the same kernel and ntp versions and I'm having no problems
at all on ntp servers or clients.

If my previous suggestions didn't help maybe you could share contents of
the following files and output of some commands so the list can see what
you've got.

/etc/ntp.conf
/etc/ntp/ntpservers
/etc/ntp/step-tickers
/var/lib/ntp/drift


grep ntpd /var/log/messages*
(please remove repeated messages for clarity)

Most recent entries in /var/log/ntpd.log

SELinux could also be playing a role.

Are you running SELinux enabled, permissive, or disabled?
What mode was it running before it stopped working?
Are there any possibly related "avc" messages in /var/log/messages
or /var/audit/audit.log?
