Thanks for the update. I actually used ODIN to go back to stock. After doing that I rooted and before installing SuperSU, I used the debloat script to disable Knox and the security updater. This has left my Note Pro rock solid and rooted with no Knox. It seems that using SuperSU to disable Knox is causing the random soft reboots.

With my P907A, it wouldn't root on our newest update. It gave me the same error. I had to ODIN back to stock and root then disable the updater using a script here on the forums.
