Hi community!
How many MACs do you have? Five or more?
Based on the ifconfig and lshw -class network outputs attached to the bottom of
this mail, there are 5 MACs in my interpretation (since the Docker one is not a
physical MAC (?) I assume).
Yea, does ethtool -T continuously change /dev/ptpX devices on you? That is
probably a kernel or driver bug…
Not ethtool -T specifically, every time I reboot the system and run ethtool -T
it displays a different /dev/ptpX device, I did run this ‘test’ for 15 times
and /dev/ptp0 never got chosen, only /dev/ptp1, /dev/ptp2, /dev/ptp3 and
/dev/ptp4 where /dev/ptp1 and /dev/ptp3 were only chosen one time each and the
rest it was always /dev/ptp2 or /dev/ptp4..
Are you passing only one ethernet device to ptp4l? Or changing? It seems very
suspicious if it keeps changing /dev/ptpX devices for a given interface. This
smells of a potential driver issue.
No, just one: enp0s25
Well, /dev/ptp0 isn't connected to the network interface you are using ptp4l
for.
Seems like it indeed isn’t. However, /dev/ptp0 is the only device that is
actually able to synchronize with phc2sys; all other /dev/ptpX devices are
never reaching servo state s2 and alway return insanely high offset/freq values.
Try Richard's suggestion of automated mode, and see what happens?
Same thing as described right above here: extremely high offset/freq, never
reaching servo state s2.
Any chance you can give us the device id for which specific device you're using?
I ran # lshw -class network and attached the output in this mail below. The
bold text is the interface I am using (enp0s25).
