Public bug reported:
After upgrading an i386 ubuntu server from 8.10 to 9.04 I started
getting these errors any time I tried to transfer a useful amount of
data -to- the system via ssh:
Received disconnect from X.X.X.X: 2: Corrupted MAC on input.
lost connection
The problem only went away after I used the following command to disable
rx-checksumming on the ethernet interface:
sudo ethtool -K eth1 rx off
I have also seen corruption in .deb packages downloaded during apt-get
upgrade which I -had- been assuming was a problem in the packages on the
update mirror my system happened to contact but which would be more
consistent with this being a problem with the r8169 driver locally.
