This is a very stable rom. I must say you did a great job. The only problem I've had is something likely unrelated to the rom itself. One of the custom lock screens from MIUI will show extra slide unlocks when something pops up, like SMS. So if I slide on the SMS part from the lock screen, it pops the message up for a second and then the phone restarts. I'm guessing that has to do with the lock screen, since that's the only time I have any trouble.
