I've been seeing sorta similar problems both at work and school.  In
every case, for me, it turned out to be the settings on the NIC. 
Normally autonegotiation works fine, but in some cases one end will be
full duplex and the other end half duplex, which means there will be
millions of collisions.  Have a look at ifconfig to see how many
collisions or errors it's had.  If it looks like that's the problem
use ethtool or mii-tool to set the duplex mode and speed manually.  If
that won't do it there may be a module option for it, or some
system-specific way.
