The servo then tries to speed up the clock even more to correct that error, but it's already at the maximum value. The HW or driver is broken. It might need to decrease the frequency limit. The only reason your change "fixes" the problem is that it resets the frequency to a non-buggy range. -- Miroslav Lichvar _______________________________________________ Linuxptp-devel mailing list Linuxptp-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
