do you use virtualization patches? I had this issue together with 
vserver and we figured out that is was an "orphaned" mount on the device...
So perhaps you have done a bind mount that was not properly unmounted or 
similar. I also had this issue some time ago, IIRC it was a broken ext3 
implementatin that "forgot" to clear a pointer to the mount and then 
created an invalid backref.
