Network Packet errors after ...up2date

[FC4]

I installed FC4 with no issue and it has been running for a month. 
Just got everything running good.  So what did I do?  I selected up2date and pick all. 

Now I get the following network errors. System is running 98% idle..

ifconfig eth0

SSH is unusable as it is to slow. 

I have changed out ethernet cards ,cables and move 
it to another network switch with no change.

Any ideals?   

Thanks..
