mismatch_cnt != 0, member content mismatch, but md says the mirror is good

Grub shouldn't make /dev/md0 inconsistent (though it ought make the boot
sectors of the two drives inconsistent).
grub-install /dev/md0
should re-generate the stage2 from /usr/share/grub, so if you drop
either mirror half and re-add it, and re-install grub then things
_should_ be normal.
Now, do we know what kind of ECC the drive does? It sounds like a
multi-bit error wasn't handled (or the ECC electronics are failing in an
infuriating fashion).
