That smells like a race in the AB code instead of the kernel being
confused over the state of the file system, and the best a sync can do
is reduce the window of failure at the cost of a potentially very
heavy IO burst.

I'd say drop this and if the problem occurs again, attempt to diagnose
where the race is.
