Comment 14 for bug 1655348

I did some more experimentation. I did not get any system freezes when I shifted down to kernel 4.8 from 4.10, where I got a lot of freezes. In kernel 4.8 I get the same output when I run sudo systemctl status gpu-manager.service as I reported for kernel 4.10 above. This might indicate that this output isn't pointing to a system-crashing bug, but I'm not certain. In 4.8, the game periodically freezes but after a few seconds the screen flashes and suddenly it unfreezes. My guess is that the same bug that causes the freezing occurs in 4.8 but the system has some code that unfreezes the computer.
