I have two Antminer S2s.  Both misbehave the same way with p2pool.  Within minutes of pointing them at p2pool, my hashrate drops to 930gh/s or lower. 

It shows this way on p2pool, on the S2 LCD, and on the S2 web UI.

It stays this way, or gets worse, as time goes by.  I've run against p2pool for days this way trying different things, and the result is always the same.  Yet running on a conventional pool (like Eligius), things run fine immediately and ongoing.

I've tried adjusting my pseudo share size.

I've tried running on a local node, my public node (other side of the country), and at least one other public p2pool node that was close to me.

Since S2s use cgminer, I was hoping a dev might be able to shed some light on this for me.

BTW, my S1s work fine with p2pool.  At 1/5 the hashrate, but they do work fine.


I apologize if this has been mentioned already.  I stopped following this thread a while ago.

Thanks.
