Comment 723 for bug 1690085

So since October of last year I was having problems with my Arch + KDE build freezing at idle on my 2700X build. Usually freezes occur while a YouTube or Twitch video is playing. When it freezes, it would often also cause whatever audio that is playing to loop over and over. Journalctl would have no logs of anything at all after the system freezes.

To fix this problem, I had to make sure that both Power Supply Idle was set to 'Typical' and that my VCore undervolt wasn't too aggressive. Both of those had to be satisfied, because for a time I only set Power Supply Idle to 'Typical' while leaving my undervolt at -0.75V, which even though it gave me no problems when the system is stressed (such as running Prime95 for close to 24 hours), it would cause the system to freeze at idle. All freezing stopped once I reduced my undervolt to -0.6875V, and the system has been running for close to 3 months now for 16 hours a day without a single hitch.

Just to be doubly sure that a fix has to require Power Supply Idle being set to 'Typical', I disabled it yesterday (while leaving my undervolt at -0.6875v), and it froze within a day.

TLDR: Setting Power Supply Idle to 'Typical' and making sure that I wasn't running an overly aggressive VCore undervolt was what solved my freezing issues.
