Smells like the same problem I reported twice here. Seems there is a fix
out there (see the archives), but Ingo Molnar has not turned up on this
list for a long time now and, personally, I don't use RAID code that
none of the maintainers/developers have looked at. Looks like the 2.2.
raid patch is abandoned. Yet, maybe the fix will be in the 2.2.18 patch
(for one that might be made against the pre series look at
ftp.kernel.org/pub/linux/kernel/people/mingo/ or so).
