This is most likely a driver issue as the log message suggests. The CM4 HW timestamping support is quite problematic from what I read. If you are sure it's linuxptp, you can try git bisect start v4.0 v3.1 and follow with git bisect good or git bisect bad after testing each step. In about 7 steps you should have the offending commit. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
