I've had a similar issue with an MCP55 ethernet driver, on a different motherboard (a generic PC one) in a more recent kernel -- after about 250 days of uptime, receiving about 70-80GBytes/day, transmitting about 90-100GBytes per day the network just fell off, not even responding to pings
ifdown eth1 worked, but ifup eth1 hung, a reboot brought the machine back.
