This is a Dell Poweredge 2800, what I've also read is forcing the CPU to stay at full speed can stop it which would be a ok temporary solution for me as it's more important the server works, but seems that scaling isn't available in Server ? Either that or it's handled differntly fromt he scaling governors like it was before:

Just to add this never occurs right after or during boot, it can take several hours to occur. I haven't spotted a pattern yet but I'll keep my eyes open.
