I've also been getting this problem on my machine possibly a little less frequently with 3.x kernels, I'm currently using the following kernel
Linux debian 3.1.0-1-amd64 #1 SMP Tue Nov 29 13:47:12 UTC 2011 x86_64 GNU/Linux network card: 05:00.0 Network controller: Atheros Communications Inc.

Having my net connection die randomly is getting really annoying. I am willing to collect more info if required. Kyle
