Slight mistake: the kernel is not in the root filesystem, and does not
reside in a JFFS2 partition.

Anyway, exposing the bug does not depend solely on whether the root file
system is one of the JFFS2 partitions being exercised in the test.
(Only tested in one direction: in a configuration where the bug does not
show up I moved the rootfs from the SD card to a JFFS2 partition on the
NAND.)

I'll be trying out various kernel versions next. Hopefully I'll find
something isolated that can either be backported or at least convince me
that this is in fact a JFFS2 bug and support me switching over to UBIFS.

Thanks,
