Ven, thank you for reporting this and helping make Ubuntu better. Given you are using an unsupported kernel, non-default kernel parameters, etc. if possible, it is best to get the computer in a stable state without WORKAROUNDs/unsupported software, and then reassess this issue.
Hence, to see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Description changed: - I have my new laptop, Lenovo 720s-13ARR shipped with the latest Ryzen 5 2500U, installed Ubuntu 17.10, it seems everything works except Wifi and GPU. After changing the wifi card with Intel 8265 and manually upgrading kernel with M-bab's build from 'https://github.com/M-Bab/linux-kernel-amdgpu-binaries'. Wifi and Gpu are working. But if I use mpv playing a video, when I try to resume the window from fullscreen, the screen freezes. Same thing happens when I use cheese, the camera app. Nothing I can do except a hard poweroff. After suffering that couple of times, I started to look for solutions from Internet. There are many error messages I can see if I use 'dmesg -l err' in the terminal. I cannot solve most of them, only use pci=noaer in the grub to suppress the "PCIe bus error", which keep increasing my "/var/log/kern.log" file size hundreds MB per hour before. - One more thing, if I start a reboot, the laptop might have a random hang on ubuntu logo screen. To avoid this, I have to poweroff first, then press power button to implement a 'reboot'. No idea for me in which part problem should be responsible for these failures. + When using mpv to play a video fullscreen, when I try to resume the + window from fullscreen, the screen freezes.
