Hi, this issue sounds rather strange. Regarding IP, ptp4l only uses UDP multicast and unicast, so TCP traffic for SSH should never be disturbed. One wild guess from my side is that ptp4l triggers some bug in your setup. Maybe the network driver for your hardware or the hardware itself behaves strange once timestamping is enabled by ptp4l.
