Server Unresponsive after kernel: PM: suspend entry (s2idle)

Featured Replies

I updated to 6.11.1 10 days ago and have been having random server lock ups happening.  It appears to be happening after this entry in the syslog:

  • kernel: PM: suspend entry (s2idle)

 

To fix the issue requires a system reboot.

 

In my problem solving attempts:

  1. I changed the mobo c-state entries:
    • Global C-state Control: Disabled (changed from Enabled)
    • Power Supply Idle Control: Typical Current Idle

 

I am not sure what else could be causing this; please help.

 

I've included system diagnostics download and syslog pre- and post- server freeze up.

Uninstall the Dynamix S3 sleep plugin and try.

Just uninstalled the plugin.  The lockup has been happening during sleep hours so I'll report back after a couple of days to see how the server operates.  Thanks for the quick reply @JorgeB

To close the loop for others that might experience this.  Ever since I removed the plugin, my server has been rock solid.  Thanks @JorgeB
