Hello Christopher, thanks for your replying. Actually I am using it after failing with ubuntu 17.10. I have to use non-default kernel parameters, or my laptop will not boot at not. the screen will freeze with the "PCIe bus error" message. With these parameters, the laptop may be successful to boot. But still, sometime fails.Once it boot successful, the mpv is OK, the problem is gone. BTW,I am using the official kernel 4.15 now.What can I do further.

Status in xorg package in Ubuntu: Incomplete Bug description: When using mpv to play a video fullscreen, when I try to resume the window from fullscreen, the screen freezes. Same thing happens when I use cheese. Nothing I can do except a hard poweroff. I've manually upgraded my kernel with M-bab's build from 'https://github.com/M-Bab/linux-kernel-amdgpu-binaries'.
