One thing I see is different on my N9, with the home partition:

I have:
/dev/mmcblk0p3 on /home type ext4 (rw,noatime,errors=remount-ro,barrier=1,stripe=8,data=ordered)

You have:
dev/mmcblk0p3 on /home type ext4 (rw,noatime,errors=remount-ro,barrier=1,data=ordered)

The option "stripe=8" is missing on your mmcblk0p3, but it does exist on your root device mount. I am not sure if it is significant but at least it is a difference.
