I think we're good for now, then -- hopefully anyone using a UHS card on their laptop will see the printk when wondering why their performance isn't great and get in touch with us, and we can investigate more then. I've pushed Manoj's patch to mmc-next for 3.1 now, with the printk changes and a stable@ tag. Thanks again, - Chris. -- Chris Ball One Laptop Per Child
