Also, can you reproduce the problem with the nobarrier and
journal_async_commit options *removed*? Yes, I know you have battery
backup, but it would be interesting to see if the problem shows up in
the default configuration with none of the more specialist options.
(So it would probably be good to test with journal_checksum removed as
well.)
I'm going to spend some time after work today trying to reproduce this
in a virtual machine. If rebooting while umounting is truly all it
takes, as it seems, this should eliminate a bunch of variables and make
it a lot easier to reproduce. (Assuming Eric hasn't already done just
that, that is.)
