Can you reproduce it on a mainline kernel? If so, can you apply the three patches in this thread: http://marc.info/?l=linux-fsdevel&m=128920213904443&w=2 and see if that fixes the problem? Also, if you are writing new test scripts that demonstrate problems, it's handy to attach them to your bug reports, or better yet, send patches to add them to the xfstests suite....
