Yep. Global C-States and the “Typical Idle Power” setting is what he’s referring to. These are common settings people have found help resolve their lockups on Unraid-Ryzen.
I went through these settings as well…in the end for me…Organizr docker container was the cause of my issue. Something possibly to do with their PHP version. From the look of your syslog crash though, I’m doubtful you have the same problem I did though. My syslog showed a CPU taint with php being the culprit.
Organizr devs are aware of the issue and are researching it.
