Comment 231 for bug 1690085

I just wanted to chime in as well. I have an AMD Ryzen 1600, ASRock X370 Taichi acting as a NFS File Server. It is running Ubuntu 17.10 server with I believe kernel 4.13 or whatever the latest kernel is after updates. Recently I have been experiencing the same exact issue as you all. Within 24 of the system being idle or low load the system just freezes. I am unable to access it. It actually happened today as I am typing this, I am unable to remote into it but I have it hooked up to a keyboard, mouse, and monitor. When I return home I want to see if there are errors of anykind on screen. I initally thought it may have been due to some hardware changes but it just didnt make sense and then I found this thread.

I am going to try disabling the C6 State and see if it helps at all and will report back. Hopefully this gets fixed with a BIOS update or something. This is a major inconvenience for server use with frequent idle loads. Thanks.
