PC: ASRock A320, R3 2200G, 2*4G DDR4, M2.NVME(windows10), HDD.

Boot from UEFI USB Ubuntu and click install ubuntu, then there is the error message:

vincent.liu, I know little about Linux and nothing about your error, but Google knows lots about this error.  Please see here.  Enjoy, John.

maybe someone is interestet. i ran ubuntu with the ryzen3 2200g right now.

i switched the vga mode with a dvi to hdmi adapter cable and now ubuntu startet with the acpi error but then

automatically get into the desktop gui without any error messages

my recent mainbord is a Asus A320m k and bios vers 4011

maybe it helps others. the ram is 8gb ddr4 2400  two 4 gb modules

good luck
