Subject: kobject_add failed for vcs1 with -EEXIST, don't try to register things with the same name in the same directory.

Got this when shutting down with 2.6.17-rc4-git2:

kobject_add failed for vcs1 with -EEXIST, don't try to register things with the same name in the same directory.

Any idea what it's about?

Thanks,
