OPi Win boots legacy but not mainline?

[Angelo Yang]

So I have a weird problem that I haven't seen yet, so forgive me if its already been answered. But for some reason mainline kernels (bionic and stretch) both bootloop at the same place. Seen below:

 

The board boots perfectly fine on legacy kernel though. I'm using decent quality Samsung SD cards, and I've tried every combination of usb cable/powerbrick as well as the barrel jack so I'm not sure what the snag is.

My OPiWin is booting fine with U-Boot v2018.11 and Mainline kernel 4.20.2 ...
