Your 8m cable length is not an issue - is this a pre-made cable or one
you made?

Sounds like you might have a duplex mismatch - you can use "ifconfig -a"
and look for excessive errors - if you are connecting to a switch you
should see none - if you are using a hub a few errors are OK.

Check the speed on the Fedora end using "dmesg | grep eth0" to see it
it's 10-half, 10-full, 100-half or 100-full duplex - make sure your
switch is the same.
