Unfortunately, there's no reliable way to reproduce it, but similar issues happen quite regularly. There were at least 9 cases since I reported the bug. Sometimes the system freezes completely and I have to restart, sometimes only one process gets killed, while its window is still there, doing nothing and being gray. The grayed-out window's owner (from `xprop | grep PID`) is always PID=13, which is always [cpuhp/1]. Oh, and also, when I say the system freezes completely, it sometimes might not be entirely true: sometimes I have a web server running and it still responds to requests; if I have music playing, sometimes it continues to play even after the freeze. But the system doesn't respond to any keyboard or mouse events.
I updated the kernel to 4.10.0.20.22 on 2017-04-28 23:44:32. Subjectively, the issues became even worse and more frequent. I save syslogs after every freeze or similar event. I will post them after I prune them. I'm not sure though. Should I post all of them in this issue or create a new one, which would describe the bug more accurately? After all, this bug is about a process getting killed after a short freeze, not about permanent freezes, even though I encounter both. Also, am I the only one affected?
