I tried different SD cards and power supplies, too.
The attached logs were done with the debian-mate-jessie-20160501-lenny.raposo-longsleep-pine64-8GB.img image on an Samsung EVO+ 32GB µSD card.
Only power, the SD card and the serial console were connected to the Pina A64 1GB.
I attached the serial console logs without (OK.txt) and with (FAIL.txt) Wifi/BT module attached.
