The link above contains pre-compiled kernel packages for upstream kernel versions. It would be quite valuable to see whether 2.6.35-rc6 has the same problem. If that also shows the problem, then it needs to be worked on upstream. Otherwise maybe have a look at 2.6.33 and 2.6.34 to narrow things down. The ext4 changes that were backported went into upstream during that timeframe but I don't know exactly right now which portions went in at which time. Having a few more pointers would help to narrow the search for other changes.
Thanks a lot for testing Patrick. It would be awesome if you could help out with some some more tests.
