That shouldn't be necessary if I understand this correctly. Have you tried using smaller PI constants, like P=0.1 I=0.001, or P=0.03 I=0.0001? -- Miroslav Lichvar _______________________________________________ Linuxptp-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
