It's not about ifb0: this report shows loopback_init after some action
on eth, so eth was probably up before lo. And of course you are right:
this warning shouldn't be there. But, since this report looks very
strange, I wonder if there could be something else that mislead
lockdep. Could you try to reproduce this with 2.6.24.2 without these
additional patches?
