Thanks for the input.
Tried this on -rc6, it behaves worse. Besides the earlier warnings
  EXT3-fs warning (device sdb4): ext3_rename: Deleting old file (268753), 2, error=-2
I also get a lot of these
  EXT3-fs error (device sdb4): ext3_add_entry: bad entry in directory #268753: rec_len is smaller than minimal - offset=56, inode=8026488, rec_len=0, name_len=0
and these at the end of the test:
  EXT3-fs warning (device sdb4): ext3_unlink: Deleting nonexistent file (268761), 0
  EXT3-fs error (device sdb4): ext3_readdir: bad entry in directory #268753: rec_len is smaller than minimal - offset=56, inode=8026488, rec_len=0, name_len=0
  EXT3-fs error (device sdb4): empty_dir: bad entry in directory #268753: rec_len is smaller than minimal - offset=56, inode=8026488, rec_len=0, name_len=0

The FS is still mounted rw.

Like you, I rerun rename14 stand-alone at the moment.
I didnt do an explicit fschk between all runs, but I also did 2 reboots
which did check the FS.

I'll try to bisect the original ext3_rename warning further.
