I am switching beta building to sunxi-4.18 branch where Allwinner NEXT (sunxi and sunxi64) is getting an upgrade directly to 4.17.y ... I made a few tests:
Cubietruck: wlan fails http://ix.io/1fYS USB OK, HDMI yes
Bananapi R40: http://ix.io/1fZm USB OK, HDMI yes
Lime A64: USB no, HDMI no, wireless buggy, eMMC yes
Orangepi prime H5: OK http://ix.io/1fZJ DVFS no
Orangepi2e: DVFS OK, HDMI OK, net OK, wifi OK, eMMC ok, http://ix.io/1fZT
Please report your findings ... after you boot into the new kernel ... currently building.
