I think they have tried some way to band-aid everything, for some reason the new cgminer binary takes a good 10 seconds to even start now, plus you get a stratum disconnect instant reboot. I had been using a proxy to switch pools now it causes a reboot. I only have 2 boards upgraded hope the jig shows up soon but now having to run the new software makes a lot of work I did useless if it is going to reboot my machines all the time.
I don't know, getting about frustrated I hope they let the code out, even if to a few people I would like to know what is going on with this, why there are so many external support programs that they run and why on earth do we need to reboot when there is a slight issue, I might need to test a little more to make sure but it did look like that is what is going on.
Edit
Does look like any type of connection issue now reboots the Pi, internet goes down, reboot loop, pool goes down reboot loop. Why we decided to do this I have no idea.
I feel your pain, been suffering off/on with same kind of issues.
Here is what I know: I know that Innosilicon is actively working on the problem(s) so good news there. I've detailed my issues to them as well as posted about them here in some other threads.
Bad news is we are in "hurry up and wait mode" -- No sarcasm intended here, I call it the "reboot dance" when it gets into the mode where it doesn't want to cooperate. It's like trying to get rabbit ears on a TV to get good reception, sometimes you have to stand there with 1 leg and 1 arm in the air to get it to do something different...
I know they are in process of shipping 2nd Jig to USA
