My best guess is that the bad block info is stored differently than
what the current INFTL code can deal with then. I have only used it
on the Disk-on-chip Millenium+ parts, and the bad block table is stored
in the factory reserved region on those parts (which I believe is
different to their other DoC parts).

Can you fully restore it with the M-systems tools?

You will need to debug the INFTL init logic and figure out what how
the initial block layout is different.
