Hello There,
I'm getting headaches again.. The stability of the miners lasted so far. Everytime I install updates on my Raspi the whole farm crashes. After the current Raspbian update I only can get one of my miners up and running the other 3 goes straight into zombie mode if I plug them in. (Doesn't matter if all at once or one after the other.) Sometimes CGminer says can't find the miners, than it suddenly finds them, ramping up beginns but suddenly stops and the program disables, resets them straight away and turns them into zombie.
I haven't changed anything on my setup (miners, miners's settings, fan, hub, PS etc.). The only thing has changed is the software (either RPi op sys or CGminer) so it must be the black sheep. Not being a programmer cannot define what component is causing my and others "instablility-problems" but I'm 100% sure now, that - as I suspected - the software is the scapegoat.

I'll wait a few days and start again, maybe it'll be fine by than, as it happened to be a week ago after the previous update as well...
