Ok, I managed to get rid of "self-destruct" message and possibly of 
segfaults by replacing kill_litter_super with kill_block_super
See: http://www.aleph1.co.uk/pipermail/yaffs/2004q4/000887.html

Now, 
1. On remount I am getting messages like:
yaffs: Allocation block 20 was not highest sequence id: block seq = 655359, 
devseq = 269156351
2. Some writes produce
**>> yaffs chunk 686 was not erased
<repeat N times with incremented chunk number>
3. Files after remount/reboot contain all zeros or disappear.
