We might have a break in this bug.   For those people who can reliably
reproduce the problem, are you using ecryptfs, possibly extensively?
Roland Drier has reported a potential lockdep report that might explain
why some of us have had extreme problems reproducing the problem; namely
we might not be using ecryptfs.   See:

http://lkml.org/lkml/2009/7/4/93

If so, there is a sample patch which **might*** fix this problem.   See:

http://lkml.org/lkml/2009/7/5/79

Also, if people could try building their kernel with
CONFIG_PROVE_LOCKING, that would be interesting to see if we get a
lockdep report.

If so, it might be that this bug has been around all along, but it's
something about Ubuntu patches that makes it 100,000 times more likely
to trigger.   (In practice, it looks like it should only trigger on a
truncate to a size which is not a multiple of the filesystem blocksize,
not on an unlink --- but maybe there was a bug in the Ubuntu backports
that made this possible to trigger on an unlink.  This is only a theory,
but it's the first lockdep report I've gotten that could at least
potentially be related to this problem that to date, only Ubuntu users
have been complaining about, even though at this point we've got a huge
number of Fedora 11 users using ext4 w/o any problems.)
