Hello,

The reason of my writing is that an error message of our webserver asked me to do so.

We're running a dual Opteron system and when booting up, the following error is shown. It's in no way critical to the operation of the system. Everything works normal.

Output of dmesg:

Do you want to look further into this issue? Can I help you with this?
