The INFTL code is telling you that it didn't think the chains
where logically correct. So it went ahead and tried to fix them up.
Once fixed you should not see any messages on the next boot (as
you didn't). Certainly not normal (or good).

I take it you are running this on a device that was formatted
using the M-systems tools?

What kernel version are you using here?

Greg
