Thanks for the suggestion! I actually started writing as a follow-up to your 
thread, but since you started out with v36 and ended with v35 I started a new 
one (I started with v35 a couple of times right away)

If I understand correctly, you now use UBI, not jffs, don't you?

If all goes well, I can send "success" in a couple of minutes :-)
