consistent mismatch count on a kernel RAID1

I've got two partitions in a RAID1.  cat'ing the mismatch_cnt for this (the only) array is now producing 122 consistently.  I've tried:

- echo'ing repair and check into sync_action for this array many times.  A cron job used to do each once on different nights of the week, now it's doing repair nightly
- running smartctl --test long on both of the HDs that have these partitions
- starting the system from SystemRescueCD and doing fsck.ext4 -fvvck

I don't know how to see any results from the repair/check actions.  The SMART test results indicate no problems on either physical HD.  The filesystem check produced no errors.  Does anyone have any other suggestions as to what I might to do fix this?  This is my root partition, not a swap and there's no swap file on this filesystem.  After a reboot the mismatch is 0 until I do a check or repair, then it's 122.  The system is an up-to-date 64-bit Arch installation, the filesystem is ext4 mounted with defaults.  Thanks.
