ACPI error message after S4

    • ACPI error message after S4

      Hello, I'm the new guy and have a question.
      I had to restart OMV 4 and now if the computer is running for longer than 15 minutes I get
      sleeps, following error message:
      acpi: hardware changed while hibernated, success doubtful!
      My hardware:
      Motherboard: Asus H81i-Plus
      CPU: Intel Core i3-4130 Haswell-DT
      GPU: Intel HD Graphics 4400
      Memory: 8 GB
      I can't see any errors in the log files.
      Is this error message relevant and how can I possibly suppress it?
      Please excuse my bad English
