I think there is no relation to Jffs2 image, now I show you my mtd partition:

0x00000000-0x00020000 : "Perseus Bootloader"

0x00020000-0x00800000 : "Perseus Kernel"

0x00800000-0x01000000 : "Perseus Rootfs"

0x01000000-0x02000000 : "Perseus JFFS2"

and if  you check the message you will find that "the Magic bitmask 0x1985 not found at 0x000e0014" are all in Perseus Kernel partition, moreover, I erased all the first 16M (from bootloader to rootfs) , so I think its none of jffs2.image's business  (the rootfs is jffs2 and the root filesystem )
And it still cant explain why jffs is ok.
