I actually don't really mind this patch... I would exchange these udelay() with almost anything, they look to me placed a bit random anyway (without going too much in detail). But in general, for this project, I think you are right and it's a good idea not to blindly change delay and sleeping functions without really knowing what you are doing. Andi
