Well this doesn't look exactly the same as on the system I had problems with.
But your Rx_TCO_Packets counter is 1, so this may be related
(I also got Rx overrun errors). It may be that your BMC receives the packet
and simply chooses to ignore it because it is no valid server management
packet.

Could you make another test and take a look at the eth0.info ?
I could reproduce the problem when copying a large file over NFS, but not
when transferring it via ftp. Try this a few times.
If you can reproduce you network card being stuck only when using NFS and
having Rx_TCO_Packets > 0 after it is stuck, this is it.
Then you either need tu upgrade your BMC firmware or add another network card,
which doesn't eat NFS packets.
