Chris, I have also seen this on mmc-next. >> [ 2.489403] mmcblk0boot1: unknown partition table >> [ 2.495921] mmcblk0boot0: unknown partition table Aren't these the "hidden" partitions ? Only available at boot time? I need to apply my patch to reset the boot partition -- or is that now in mmc-next to see if the problem still happens.
