After Update to 2.7 no ntp update sync, also some traffic graphs are broken

[GOCE]

I noticed today that the upgrade from 2.1.9 to 2.7.0 broke somehow my NTP settings.
I am not able to sync the time over NTP anymore.

The second thing that seems to be broken on my HA setup is the Traffic Graph. I don't see the In or Out traffic of the WAN interfaces anymore.

Are there any other reports with similar symptom's?

I also see something strange in my log

Traffic graph is a known issue when running IPS. 

Here are a few, might be more...

Can confirm that turning IPS mode off resolved the graph issues.

I tried that, didn't make any difference (and yes I did reboot after), graphs still broken.

Adding net.bpf.zerocopy_enable=1 to the tunables didn't change anything for me too.

I could resolve my ntp issue by letting the service listen again on all interfaces. Before (20.1) ntpd was listening only on selected interfaces in my setup and it worked without problems.
