The device is fairly quirky and goes into a reset cycle on a vanilla kernel. Since I had no idea how to get to the right changes at first, I ended up playing with the debug information a fair amount at first, and I thought it would be nice to clean it up to modern standard. Joe Perches suggested removing debug output redundant with ftrace (which was actually quite useful to find the right places to change.) HTH!
