Thanks for the update and congrats on your ASICs, have you run into any significant problems with set-up/firmware or have they been relatively straightforward? How solid is your internet connection and do they require restarts/maintenance regularly?
Set up has been pretty easy. It's running OpenWRT with a web gui and it seems pretty stable.
I installed the 4/10 NEXT firmware last night. After my last 18 hours of experience with this firmware I cannot recommend any other version of the firmware. This is the only version of the firmware that has seem to have had a really stable version of CGMiner. It starts right away, it updates right away, and the modules don't sit at zero for no reason anymore. For some reason sometimes the fans spin down and right back up for no apparent reason.
The efficiency seems just as high as it did before, but I'm not sure that the MHash/s is quite as high. If it is a little bit lower than it's only by a few thousand MHash/s and could be a difference in network latency or something like that and might not be CGMiner at all. I'll keep an eye on it and I might run another test later.
Avalon on Ozcoin with the 4/10 firmware is stable and recovers on it's own. Previous version hung but were stable on a private pool with eloipool. This firmware has many improvements over previous versions and my Avalon is running nicely.
