I just had a closer look and you could also set mmcblk.perdev_minors=x in the kernel cmdline, where is is the maximum number of partitions you want to support minus one. So for 9 partitions set it 10. >> When I hot-plug the card, the Nanonote tries to mount p4 but fails. >> Automounting is really confused! It mounts partitions: p1, p5, p6, >> and p7.
