Sorry :(

I used the davem patch, the second version of your first one, and your second 
one. Both problems persist.

Still plugging away on bisection.
GIT bisecting the lockdep problem is surely going the land you on:

commit e308a5d806c852f56590ffdd3834d0df0cbed8d7
No. It landed on this one.
For the lockdep warnings?
When I was just one commit later, I got both the lockdep warning and the BUG. 
This is the commit in question.

     pkt_sched: dev_init_scheduler() does not need to lock qdisc tree.

     We are registering the device, there is no way anyone can get
     at this object's qdiscs yet in any meaningful way.
