Hi Yuguoi
Since the laptop got both the Nvidia and the AMD for graphics, can (or have you?) tried to blacklist both?
modeset=0 nouveau.modeset=0 amdgpu.modeset=0 rd.driver.blacklist=nouveau,amdgpu
on the line starting:
module2 /vmlinuz-..
I’m about out of ideas … so now it’s just random “maybe it could be”-suggestions I can give … 
As an alternative, you could try the r4.3.1-rc1 and see if an updated kernel/driver can solve the problem?
