Connection times out when transferring 2 GB+ of data across network.

[JaSauders]

Ubuntu 13.04 64 bit, February 27th daily image. I installed this same ISO on my laptop and desktop. On both of them if I copy at least 2 GB of data over the network to a different location, they lock up right around the 2 GB mark. The transfer stops and eventually I get an error citing that the connection timed out. Whenever this happens it seems as if I have to restart to regain network connectivity.

At first I thought this was a Nautilus or Samba thing, as it first surfaced when I was pushing about 10 GB of data from my 13.04 desktop to my 12.04 Ubuntu Server. However, I tried this using rsync over SSH and it did the same thing, indicating it's not likely a Nautilus or Samba issue.

I also thought it was the hardware of my desktop, but like I said, I tried my laptop over wireless and it did the same exact thing. I've seen it happen when the file transfer gets to 2.0 GB or 2.3 GB. Somewhere in there is when I've seen the error pop up.

I ran dmesg on my desktop after this happened. I was spamming dmesg as the data was being pushed over the network and I was getting the same output each time, but the second the issue popped up is when the list of DMA entries popped up.
