I suggest you try software timestamp (add -S switch). I have a panel PC at the office where I installed Ubuntu and to my surprise there was no hardware timestamp support (Intel CPU but Realtek Gbit/s Ethernet controllers) whereas on another AMD based SBC with Intel Ethernet controllers, hardware timestamp worked right away with Ubuntu unmodified installation. Maybe your PC has one of these Realtek controllers as well (from memory, when I researched on it, there were issues with Realtek controllers and PHC support) or another controller not well supported.
