Hi Robert,

Ok, I think I have identified the issue, and I probably can reproduce
it with the board I have. I think this is a regression due to a
recent fix, when I changed the ->correct() hook to check for 0xFF bytes
also in the ECC bytes.

I will come back to you in a few days, until then, happy end of year :)

Thank you,
