Depends on which APU you have and which features you need. The latest Raven Ridge APUs had stability problems until 4.17, anything older should work on 18.04 which ships 4.15. HDMI/Displayport audio support for the older models landed in 4.15 but wasn't enabled by default until 4.17, so in 4.15-4.16 you have to pass the amdgpu.dc=1 kernel parameter for it work.
