Yep. Ideally would be to write a test case which runs on the synth
target. We can all work with that. This does work, i've run the
standard test case on synth before.

Actually, it could be ecos specific. There is an wrapper round jffs2
which implements the interface between eCos fileio and jffs2. The
problem could be in there. Also, its easier to debug jffs2 in eCos
than inside a linux kernel.
