JFFS2 noise okay or a problem?

Hi folks -

I don't know if it is because I am running a config the hardware ECC
that made trouble for Werner and Xora, but I am noticing some sticky
warnings coming from the rootfs JFFS2 and the return of an error that
disappeared for a long while.

Initially these Empty flash notices disappeared entirely after using the
canned filesystem from Werner, now there seems to be more of them.  But
it is true I am randomly resetting the board all day.

The failure of the garbage collector to fork has reappeared as well.

The filesystem is not blowing chunks so maybe it's all fine... Googling
about the "Empty flash" thing says it is "harmless".

Does this represent a problem or is it okay for us?
