I can't help but notice that you seem to get the same address in 4
different logs - if it really is that deterministic then that's quite
the boon for debugging (FWIW my first thought is that it looks a lot
like a phys_to_virt() of something bogus). I've never used kmemleak
myself, but looking at where it's crashing it appears to think that that
address is a valid object - if I'm reading the docs correctly then I
guess the "dump" command ought to be able to tell you where it thinks
that object came from.
