Are you sure the disk is good? I just checked the code in e2fsprogs, it
seems that it will not complain if rec_len = 0, and the dir iteration
just aborts.

Um, where are you seeing this?  It should be complaining that the
directory entry is corrupt if rec_len < 12.  I believe I see the
checks there, but I haven't tried creating some test file systems to
be sure.

Oh, sorry my fault. Yes, I see a final com_err in the end of do_list_dir
in debugfs. So we should complain about the dir corruption.

Thanks
