kernel errors?

    • kernel errors?

      Periodically I see a whole mess of errors in my syslog. Here's a small sample. Is there a potential hardware issue?

      SAS HBA is a Supermicro AOC-SAS2LP-MV8 on an Asrock H270M-ITX mobo. Haven't noticed any system stability issues or any issues whatsoever.

      Thanks
