Ahh, I see now. You seem to have two conflicting partition tables on
the drive. The MBR/DOS one, and an Acorn partition table. The newer
kernels are recognizing and using the Acorn one. You will need to get
rid of that. From what I can tell from a quick glance at the kernel
sources, its primary information is stored in sector 6. Zeroing that
out with dd should get rid of it.

Title:
recognized partitions incomplete on 14.04.2 and 15.04
Status in linux package in Ubuntu:
Invalid
Bug description:
on ubuntu 15.04, 14.04.2 the system shows me after plugging a SD card
the following information (where sdc the SD card is)
me@my-Linux:~$ cat /proc/partitions
major minor #blocks name
...
8 32 15558144 sdc

me@my-Linux:~$ sudo fdisk -l /dev/sdc

Partition table entries are not in disk order.
none of the partitions are able to mount.
the exact same SD card and same USB/SD card reader but using ubuntu 14.04 or
12.04 shows me the correct information:
me@my-Linux:~$ cat /proc/partitions
major minor #blocks name
...
8 16 15558144 sdc
8 17 121046 sdc1
8 18 1 sdc2

8 22 6639616 sdc6
8 23 61440 sdc7
8 24 8519680 sdc8
