Well i don't know what this message is causing. But did this message occur after a fresh install or on a running server? &nbsp;Did you check the logs if the message appears just while booting or in a regular manner? Do you have the latest updates on your Ubuntu Server? Did you check the hardware with some hardware check program? If you have time you could use a new HDD with a fresh install of Ubuntu to see if this error still occurs? You could also make a backup of your system and update your Ubuntu to 10.0.4 LTS since this error could be kernel based?t <br />
<br />
these are just suggestions no real masterplan.<br />
