XFS delaylog wasn't the default until 2.6.39.  I think it was introduced
as experimental in 2.6.35.  It may not be relevant to your current
issue, but were you mounting XFS with delaylog?

I agree with the others.  Upgrade to a much newer kernel.  Why are you
using 2.6.35?  It's very old, it's an oddball.  AFAIK no distros use it.
