I've had somewhat similar issues (ssh getting corruption in its data stream) 
when a NIC in my netbook was corrupting packet data when it ran at 1G (it 
worked fine at 10/100).  Pyun eventually fixed the issue by applying enough 
workarounds (it was likely a hardware bug in the NIC's chipset).  However, it 
wasn't easy to debug unfortunately. :(
