Thanks for your response. This issue is observed on NIC PHC and apart from ptp4l no other process will update the NIC PHC in this case.
Will process (ptp4l) scheduling have an impact on this? regards, Ramesh On Wednesday, August 3, 2022 at 12:03:10 PM GMT+5:30, Miroslav Lichvar <mlich...@redhat.com> wrote: On Tue, Aug 02, 2022 at 05:42:55PM +0000, ramesh t via Linuxptp-devel wrote: > Hello, > > Observing once in while clockcheck error. > > Any suggestion why this could happen?? On what hardware? SW or HW timestamping? It could be a driver bug. It could also be another program adjusting the clock, like an NTP client. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
