I have been mining with Gridseeds, run by PC, using bfgminer.
Now I am trying to learn to mine using Raspberry Pi.

I have tried the GAWminers img, and the Zoomhash img, and I have built several Raspbian Wheezy systems myself.  I have tried installing a python stratum proxy.  I have used cgminer and bfgminer.  I get the same results no matter what I do:

I connect to a pool, I get no Accepts.  (I have tried various pools, including this one, but I mainly use a different pool so I can watch my dashboard on it to see hashrate...)

I restart the miner, sometimes I get one (1) Accept, then no more.

One time, using cgminer, I got quite a few Accepts in a row.  In fact, I got 32 Accepts each time my work was accepted.  When the number of Accepts got to 1072, it stopped.  (I realize 1072 is not a multiple of 32, I'm just telling the truth...)

I am not looking for anybody to help me debug and such, I am just hoping that my situation rings a bell with you.
