2.6.32.16 is quite old, why are you not running the latest stable
release? There have been several fixes to migration since then.
I'm a bit confused though, 8a22b9996b001c88f2bfb54c6de6a05fc39e177a only
went in at 2.6.32.18 (as 9c55fad24be2f417233f5ea3959ade85756fda5f) so
should make no difference to 2.6.32.{15,16}.
Ian.
