I assume you're using the new NAND-based diskonchip driver.  This driver 
uses a BBT scheme which is slightly different from the one used by 
M-Systems.  (Specifically:  it preserves the MSystems BBT but adds a 
backup BBT).  The messages you are seeing indicate that we haven't found 
this "Linux-specific" BBT table.  This is completely normal.

To avoid filesystem corruption, the diskonchip driver won't create the 
BBT tables it wants unless you give it permission, using either a config 
option (MTD_NAND_DISKONCHIP_BBTWRITE) or a module load parameter 
(inftl_bbt_write).  See the config help for more info.

When the Linux-specific BBT table is created, it is marked as reserved, 
so the MSystems tools won't touch it and won't be bothered by it.

I can't help you with these messages -- I've never actually used INFTL.
