The only issue I have is the Black Screen of Death issue. There is not really a particular way to replicate the issue as there is not a pattern that I can tell. However if you check out steady hawkins G+ page you will see an entire thread on it where they are trying to resolve the issue. On here, XDA forums, the CM 10.1 thread is constantly talking about it. CM 10 stable also does this to me as well whereas the earlier nightlies for CM 10 did not.
Team EOS 4 ROM has this same issue it seems.
Im using a stingray device but its affecting both stingray and wingray from what I have been reading. Whatever nightly you are using I would stay on it
