OK, I've gone back to using and ramdisk for rootfs and it works! -
thanks for the advice.
It makes using nfsroot a bit more difficult as I'll have to create a
ramdisk image first and then pivot_root to nfs I guess. In the long
term, I don't see this as a problem as I'll put the rootfs into flash.

That means that I've just got to tidy the camera driver up a bit and
(finally!) I'll post a patch.
