On what kernel are you guys ?
I have 2 box on Debian 9 - 4.9.xx and it works but on proxmox 4.15.xx and on pi 4.14.xx (armhf, beta so I don't cry) nope.
Give the output of
uname -r
Edit:
After testing again actually, it doesn't work everywhere. Must be an issue with lib. Let's wait the next update.
