PoE breaks networking?

Just wondering if anyone else has not been able to get DHCP when connected to a PoE switch, I did not have this issue with Raspbian.

    Hi
    So your powering the RPI via a PoE splitter? Normally when funky things
    happen check the power supply....

    No just plugging into a PoE switch, I have a hub between it and it works. There must be a kernel bug in 4.4 or a setting somewhere that I'm unaware of.

    Hi
    So your using wicked for dhcp? Is it ipv4 or ipv6? I use static ip's
    and no ipv6 (disable via YaST network settings)

    I have around 10 of them all connected to a POE switch with no problems.

    So first suggestion I have is have you tried turning POE off on the port in question to see if that fixes things?

    What type of switch is it and what POE standard does it implement?
