Anyone else having issues with their Bitburner? Lately they will just suddenly drop to ~450 GH/sec. I have to pull the power and USB, let them sit a few seconds, then hook them up again and they go back to hashing normally. Doesn't happen to all at once, just one every now and then (I have two).

I did notice this start happening when I switched to the latest cgminer:

Code:
[2013-11-16 21:37:40] Started cgminer 3.8.2
[2013-11-16 21:37:51] BTB0: Reset failed! not an Avalon? (0: 00 00 00 00)
[2013-11-16 21:37:51] BTB0: Idling 2 miners
[2013-11-16 21:37:51] BTB0: Core voltage set to 1334 millivolts
[2013-11-16 21:37:52] BTB1: Reset failed! not an Avalon? (0: 01 00 00 00)
[2013-11-16 21:37:52] BTB1: Idling 1 miners
[2013-11-16 21:37:52] BTB1: Core voltage set to 1334 millivolts

Maybe they are reaching the cutoff temperature of 60°C?
You can adjust it by cmd line parameter.

That isn't the case because that message appears right when you start hashing so boards are cold, so maybe it's something from the cgminer because earlier versions didn't have that message.
