Interesting, didn't know any vendor had combined PCH and 82574 on one board,
yes, they are
completely different, as you can see the one only supports MSI, its a client
NIC.

I would agree with Mike, disable anything having to do with IPMI if it
exists and see if that
helps. Also you did not comment on the flow control setting, how about
turning that on?
