The lovely Supermicro 82574L bug! There was a similar thread about a 
month ago:

The short answer that's worked for me: Add pcie_aspm=off to your 
boot-time kernel options. I've also started running the kmod-e1001e 
package from elrepo.org.

Also, if MSI-X isn't already turned off in the BIOS, others have 
suggested making sure it is.
