Hi folks. I didn’t do anything unusual, I just restarted the computer after the update, launched all the applications that I usually launch and went to drink tea. When I returned, I found that the monitor was on (it should have turned off since I had set the energy-saving mode for 5 minutes in DE) I tried to move the mouse, after that I realized that the computer was completely frozen. Even Alt+PrnScr+B did not helped reboot computer. I decided to fill the bug report here since this is a really serious problem.

I think this issue related to amdgpu driver. Can anyone look into it?

Thanks.
