Hi,

I am getting the following error on server Cisco UCS C200 M2 running 
FreeBSD 8.3 amd64

# uname -srmi
FreeBSD 8.3-RELEASE amd64 GENERIC

I don't know what it means. Should I be worried about it or should I 
ignore it?
Is there something that I can tune to turn this message off or is there 
something which need to be fixed on FreeBSD side?

We are planing to push this machine in to a production in one or two 
weeks, but until this time I can test patches etc.
