A few customers have been affected by a firmware bug that can cause instability when using Intel’s C-State power-saving functionality.

BIOS:

  • Reboot the server
  • Press F2 to enter the BIOS configuration menu
  • Select Processor Settings
  • Scroll down to “C States” and “C1E”
  • Use the arrow keys to set both to Disabled
  • Press ESC repeatedly and select “Save changes and exit”

OpenManage:

  • Launch the OpenManage web interface (https://IP_ADDRESS:1311/)
  • Log in using your root username and password
  • Select Main System Chassis -> BIOS -> Setup tab
  • Select “Processor C State Control”
  • Select the “Disabled” radio button -> Apply -> “Go Back to BIOS Setup Page”
  • Repeat for “Processor C1-E”
  • Reboot the server to apply the settings change
