jffs2 Oops on 2.6.10-rc1-mm5

Hi there!
I am porting my i.MX processor stuff from 2.6.9 to 2.6.10-rc1-mm5
because I need the XIP stuff in there.
All is working well, but when 2.6.10-rc1-mm5 should mount its newly
flashed jffs2 filesystem it Oopses the way you see in the attachement.
Weird thing is, when I boot my 2.6.9 kernel for testing purposes it
mounts the / fine and after that the 2.6.10-rc1-mm5 likes the filesystem
also and mounts it.
I created the jffs2 filestem that way:
mkfs.jffs2 -q --eraseblock=128KiB -o
/home/konsti/svn/ptxdist-0.5.2-trunk/root_scb9328 -D
/home/konsti/svn/ptxdist-0.5.2-trunk/src/device_table.txt
--root=/home/konsti/svn/ptxdist-0.5.2-trunk/root
with mkfs.jffs2: revision 1.42
This is, when 2.6.10-rc1-mm5 investigates the system after 2.6.9 has
"initialized" the /:
Probing scb9328_flash at physical address 0x10000000 (16-bit buswidth)

Well, if someone might know, where an error is (may be me?), please tell
me :)
