Can you provide a little more details? The MTD / JFFS2 code in this kernel is not too old, andwe use it in a couple of projects without such problems. > waiting for GC.

We backported the MTD / JFFS2 code.

Note that log files may cause a lot of trouble when using a JFFS2 file system. Youmay want to addd a buffering layer, like pramfs in a dedicated RAM area (SRAM ideally).
