I have to use a machine with ASUS motherboard, that has age(4) ethernet adapter. It seems that active use of the net causes corrupted frames, like the following ssh disconnect (after doing find / in the shell): Disconnecting: Corrupted MAC on input.
It can't be just a packet corruption, since TCP has checksums, and corrupted packets should have been dropped and retransmitted. Try to turn off checksum offloading.
Machine runs reasonably latest stable/7. Any advice ? Anything I should try to tweak ? Do you need additional information ?
