Changes between 19.07 and master with 4.14 are only cosmetic. I don't see a relevant difference from the code.

We just discussed this in IRC and the (only) likely idea we had was NAND wear issues, i.e. some bad blocks that were not recognized during flashing.

It would help tremendously if the same could be checked on one or two additional devices.
