How about these patches?
Sorry for the earlier noise....
BTW, would you prefer that I open a new bug for this one?
Cheers,
Tim.

+DATA LOSS MAY HAVE OCCURRED.
+
+This condition may have been caused by one or more of the following events:
+
+. A power failure whilst the array was being written-to.
+. Data corruption by faulty hard disk drive, drive controller, cabling, RAM,
+ motherboard, PSU etc. etc.
+. A kernel bug.
+. An array being forcibly created in an inconsistent state using the
+ "--assume-clean" argument to mdadm.
+
+This count is updated when the md subsystem carries out a 'check' or
+'repair' action. In the case of 'repair' it reflects the number of
+mismatched blocks prior to carrying out the repair.
+
+Once you have fixed the error, carry out a 'check' action to reset the count
+to zero.
+
+Note that this check is only applied to arrays which aren't RAID1 or RAID10,
+due to a kernel limitation. See the md (section 4) manual page, and the
+following URL for details:
