Hi, Same issue with my system on motherboard MSI A78M-E35 with AMD APU A4-5300. But my system reboots some 3 seconds after initramfs is loaded. So no Xorg and no logs.
You have an APU. This bug is specifically about dpm on BTC discrete GPUs. It sounds like you are seeing bug 72921. Please try the patch on that bug.
