dmesg of loading amdgpu module

I have an AMD Ryzen 5 2400G with Radeon Vega Graphics computer.  When I use the
Linux kernel v4.16-rc6 on it, system hangs up during the booting time.

Therefore, I try to load the amdgpu module manually and found whenever I load
amdgpu module, system hangs up.  However, I can ssh into the system, after
system hangs up.

The attachment is the dmesg with the mudule parameters amdgpu.dc_log=1
drm.debug=7.
