Thus you get read errors even if there is no bad block on the disk itself. Those bad block entries can be caused by cable or controller flukes, making temporary problems permanent... Personally I disable the bad block list everywhere. You can search this list for old messages regarding --examine-badblocks, this problem came up several times. Clearing the mdadm bad block list is worth a try. There's an undocumented option, update=force-no-bbl or such.
