Thanks, I'll look into the possibilities.

I am trying to avoid the jffs2 as a prerequisite to run this
code. I had quite a few troubles with it, sometimes manifesting
as hang when mounting (debugging showed mount code going in loops
over the same data), sometimes as thread crashing leaving
the fs locked.

I traced the corruption to some problem in interrupt handling
in my SPI code (right now I am running it polled until I'll find
the time to investigate), but if a data corruption can cause
an indefinite loop, I prefer to stay away from a filesystem
or at least have a way to reformat it first.
