The bad block log misfeature is turned on.  Any blocks recorded in it will never be read again by MD, last I looked.  This might explain what you are seeing.


While I see where you are going, the fact it corrected the bad sector by re-writing it during the re-build would intimate that isn't/wasn't the case.

Ah, yes. Any chance you have set the sysfs sector limits on a check and haven't reset them?
