I'm interested in understanding to what extent the hang you see in production
on 2.6.38 is similar to the hang of the reproducer.  Mark is seeing a situation
where there is nothing on the AIL and is clogged up in the CIL, others are
seeing items on the AIL that don't seem to be making progress.  Could you
provide a dump or traces from a hang on a filesystem with a normal sized log?
Can the reproducer hit the hang eventually without resorting to the tiny log?

Regards,
	Ben
