I think that it is an SD timing issue. I can confirm that you can boot to UEFI and then insert the SD card - it hangs the system. I can also confirm that I have two systems, one of which sees and boots from the SD card and the other of which just hangs. I haven't tried using the 'working' SD card in the non-working system, but I'll try that later...

I do not try this version. But I could boot upstream kernel from sd card successful. Are you sure it is hang or it is just no output in serial?
The minicom doesn't do an I/O after the card is inserted, that's it.
Do you attach some mezzanine board? I could not find my sd card when I attach Grove Starter Kit.
I had the UART debugger board attached. It looks like some SD card timing issue here. Some SD cards don't work while others do.
Maybe it is the different issue. The UART debugger board works fine with sd card in my case.
