PC Processors

[dergatt]

Hi all,

my computer Ryzen 5 3600 randomly reboots with the microcode error message 8701021. Before a restart I get some screen flickering. The time between flickering and the reboot is not consistent tho.

I'm running Linux with the newest kernel and amd microcode.

Does anyone knows what this error message means or has a similar issue?

Well I'm not a linux user so a lot of the information I found was over my head.

The threads on this issue seem to indicate that the issue is with the CPU's low power states.

Fixes that seemed to work for people  where either disabling PBO or disabling c6 staes.
