I have had trouble with a pi, basically high usb traffic can cause the ethernet controler to drop out. I have a 20 port usb 2 hub plugged into the pi, and it will run for a while then randomly the ethernet driver starts getting errors and drops out.
This is a known issue with the pi, something to do with voltage drops. In any event i ended up using a spare old pc and throwing centos on it. USB issues gone
Ive tried doing firmware updates on the pi, and there is a kernel boot option for the nic but these make no difference.

I used to get lockup and dropout problems with my pi which I eventually solved by buffering the power through an extra usb hub which has no usb sticks in it.
So I now have a powered Plugable 7 port hub plugged into the pi and the pi takes it's power from a USB port on that.
Then I have several powered D-Link 7 port hubs plugged into the Plugable hub, with all the usb sticks plugged into them.
I believe this prevents any power fluctuations from the D-Link hubs reaching the pi through upstream power connections.
Whatever it does, it seems to work.
Interesting... I might take a look into that at some point. Currently using a spare Blackberry charger (0.7a) for the Pi, which has always worked fine when running them headless.
Watchdog seemed to catch a lockup earlier on today and automatically restart, so as a short term workaround it definitely seems to be worth trying that. (I've set it restart if load is over 70 for 5 mins)
I've also set up a cron job to ping my router and restart the Pi if that fails, and one to check if a cgminer process is running and restart if not... Quite a lot of effort, but it seems to be working OK so far
