"Corrupted MAC on input" is usually the result of hardware (network or
host) problems.

There's also a well-documented firmware problem with LinkSys routers
that is known to cause this:
there's also a couple of other possibilities here:

FWIW I tried a 5.4GB scp to localhost on a FC2 box and it worked OK.

$ rpm -q fedora-release openssh
$ dd if=/dev/urandom of=/tmp/big bs=1024k count=5400
$ scp /tmp/big localhost:/tmp/big2
big                           100% 5400MB   7.4MB/s   12:07

Works for me here as well.
