What us the NIC in the laptop ?
I've had this problem before using the open source driver for a network
adapter.

But this appears to also happen over the loopback interface.
If you can reliably get it to mess up, see what reliably never messes up,
squeeze between the two.
I reproduced the problem under Windows, with exactly the same
symptoms. But it was considerably harder, perhaps because ssh/scp
under Cygwin is a lot slower than it is on Linux, and it did appear
that the rate of data transfer affected how frequently it failed.
I did it by copying a ~36 GB file repeatedly from a known good Linux
host to the laptop, while running a load in the background (on Linux,
multiple copies of glxgears with the option to turn off sync, on
Windows, by running prime95 along with an OpenGL demo in the
background). It took me about 5 tries on Windows to finally get a
failure, but I did, with exactly the same pattern as under Linux.
Congratulations! Sounds like a hardware problem. (Unless it is a problem
in scp!)
