I have been running Armbian_5.83.190502_Orangepi3_Ubuntu_bionic_dev_5.0.10.img since it was released and have no problems so far. I wrote it to the EMMC and everything seems to work apart from the Wi-Fi. Running
cp /lib/firmware/brcm/brcmfmac4356-sdio.bin /lib/firmware/brcm/brcmfmac43456-sdio.bin
cp /lib/firmware/brcm/brcmfmac4356-sdio.txt /lib/firmware/brcm/brcmfmac43456-sdio.txt
fixes the Wi-Fi for both 2.4 and 5 GHz. However, the bit rates do not seem to be higher than 54 Mb/s (802.11g).
Iperf3 benchmark had 941 Mb/s on the ethernet port (might be capped also by my router or laptop ethernet adapter).
EMMC gets around 81 MB/s read speed.
