To reverse this, all I need to do is revert to a normal kernel, and zap the .journal file right? The next boot in the car came up to a no drives found error, and I have a feeling it's drive0 dieing. I want to reverse all the custom changes though just to make sure. (It came back to life on it's own, I heard a drive noise in the car while I was stopped, pulled the unit and reinseted it to be welcomed to my music again).
