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?
No - this one triggers the kernel BUG as follows:

I'll have to trace back to see which of the bisections produced both the lockdep
and the kernel bug.
