I would suggest opening a bug (https://bugs.freedesktop.org) and attaching your dmesg output and Xorg log (if using X). Please also attach a copy of your vbios (sudo cat /sys/kernel/debug/dri/0/amdgpu_vbios > /tmp/vbios.rom). VGA is usually implemented via a DP bridge chip since that chip does not support analog outputs directly.
