uhm, i thought it to be noteworthy.
the problem scales with the speed the packets come in/go out:
* downloads from an ftp server outside the LAN (connected with 4Mbps)
give no errors;
* transfers with a host in the same LAN at 10Mbps give rarely errors of
this kind, but they are there;
* transfers with a host in the same LAN at 100Mbps gives a busy syslogd...
the problem starts immediately, as i already noted, as soon as the ssh
handshaking takes place.
the network is useable but surely has lots of unneccessary retransmits
due to the CRC errors.
