dmesg logfile

I have Gigabyte RX460 2GB gpu card, Debian testing Xfce and adg5f
drm-next-4.11-wip kernel downloaded and compiled as today. Computer works ok
but the dmesg command shows the following boot errors that might interest
amdgou driver developers. Mounting my home partiton fails amdgpu IB tests:
