Re: [Linuxptp-devel] linuxptp on ubuntu 14.04

[Andrei P. <and...@kl...>]

I was running *ptp4l* and *phc2sys* this is what caused the behavior. But
as far as ntp goes I did not start anything myself and did not find any ntp
service in the backgorund...though I get your point a conflict between two
programs is likely to be the cause.

anyway once I stopped phc2sys after a while (about one hour) it went back
to normal...

Thanks for your help,
Andrei
