I also have this problem on an Intel DQ45CB mainboard with the onboard Intel 82567LM-3 Gigabit ethernet controller. The syslog fills up with following entries, while network connection is being reset. It does not happen immediately after boot, but high throughput seems to trigger it. I use the adapter in a bridge in a KVM server.
