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.
