I'll second the suggestion for disabling MSI-X and add one: add
pcie_aspm=off to your boot-time kernel options.
You wouldn't happen to be running a SuperMicro mainboard with
onboard Intel 82574L NICs, would you? If so, I'll also suggest
installing the kmod-e1000e package from elrepo.org, which includes a
workaround for the bad PROM that's involved.
