Sounds like the switch it's connected to is having issues with the
autonegotiation for speed or duplex settings.  That's not that uncommon
with certain switches.

You might try adding the appropriate parameters to your
/etc/modprobe.d/dist.conf:

	options e1000 speed=100 duplex=full

to remove the autonegotiation from the mix.
