Comment 12 for bug 246789

I have a similar/same error with a lenovo s10e and ubuntu 8.10: it uses the tg3 driver for the fast ethernet device:
connecting with ssh to the netbook and starting firefox or other big application in this shell, produces an
error "Disconnecting: Corrupted MAC on input." and I'm disconnected from the s10e. In other direction: starting apps from
the s10e on other machines through ssh shell produces no error.

I have found a bugfix: calling 'sudo ethtool -K eth0 tx off rx off', after calling this command no errors are produced!!!
