And if fact it does.  I found a 2.6.34 kernel and hit the same bug.

The mdadm bug is fixed by upstream commit
c03ef02d92e4b2a7397f7247ea5a25d932a1a889

It is triggered by a kernel bug that is fixed in upstream commit
    a64c876fd357906a1f7193723866562ad290654c
(and many a few near by commits) which will be in 2.6.35, and is in
the latest 2.6.34-stable: 2.6.34.1.
