I've been doing a little learning on how the __setup() macro works. A proposed solution I have is to change from using the __setup() macro to using early_param() to mark the call to cca_setup(). Functions marked with __setup() are executed late in the boot process, whereas those marked with early_param() occur very early in the process. I have tried this out, and it solves my problem, but I'm looking for feedback on whether this is the correct solution. Unless I get any different feedback, I'll send out a patch with my change later today. Shane McDonald
