I have an old Dell server (some horrific serverworks mb and an old 2.4Ghz chip on it) that I am using as a NFS server. Basically... 2 promise cards and lots of HDs.

In dmesg I get this:

My question is this.. are these irq handler mismatch errors something to worry about? And, if so, is there a way to correct it?

TIA for any help
