getting cgminer restarts every 10-60 min. I believe the longest uptime I've seen is 2hr and 2nd longest uptime is 1hr 17m.
I stopped the cgminer process that was started on bootup, ssh'd in, and ran cgminer from cmdline to watch what was happening.

I have used the latest firmware (
20130519) and also another test firmware provided to me by Aseras (050713.bin) with cgminer 3.1
Ambient room temps are about 78F.
Temps shown by Avalon are: Temp1-23 Temp2-40 Temp3-42
I have tried all clocks and I'm currently running at 256 (Normal)
Avalon team, any ideas?
TIA
With all the restarts, effective 24h hashrate is in the vicinity of 52-53GH
