Hi Justin, I think it is safe to say that Debian is not the cause. Well at least not directly. I have experienced the same issue trying to use g_ether, but find the ethernet port to work perfectly.
Long story short, My BBB came with Angstrom ( RevA bought at launch last year ), and I quickly moved to Debian. For the longest time I ran from ethernet, until I had the idea that perhaps I could squeeze a bit more performance if I used g_ether instead. What I found was similar or perhaps exactly what you're experiencing. The connection would stop responding after a short period, and would not work again until I ping'd each way from the command line. After which the connection would shortly stop responding again. After a few days trying to troubleshoot the issue, and calling no joy I switched back to ethernet only, and have not had a problem since. I have my suspicions that this problem is either related to to a few things but the g_ether software running on the BBB comes to mind first. Other possible suspects would be a faulty USB cable ( working well enough to provide power ), or the Windows drivers on the PC side. But I am fairly certain your ( and mine ) BBB's are fine, as well as the PC' they're connected to.At least my own laptop the BBB connects to works perfectly in every other aspect.
