Hi,
could you check the mtu set on eth0 with an ifconfig?
I tried my own setup and it works fine...

Eric, here's the information you requested with the mtu set at 1500 (see
further below):

Gypsy, I've been playing with the mtu settings. I had initially set it to
1500, which is what the card should be at as the switch I have does not
support jumbo frames. If I set the mtu to 40,000 for the class the giants
go away and everything seems to fall back into place. However, this seems
waaaaay off what it should be, do you have any idea whats happening? I
cannot seem to adjust the mpu setting.
