Hi Badari,
Thanks for your answer.
I didn't reproduce it without the latest ext4 patches. So I suspect a
bug in one of them.
But how debugging this?
Which other debug traces can I turn on?

Let me understand. You applied latest ext4 patchsets ? If so, Mingming
has some slab-cleanup changes in the patchset. You can try backing them
out and see.

It's unlikely to be the jbd_slab_cleanup.patch, which actually get rid
of slab allocation for buffers passing down to disk IO, and replace with
get_free_page directly.
Could you send me the profile used for ffsb test?
Thanks,

While running ffsb tests on my ext4 filesystem, I got an Oops in
cache_alloc_refill().
I turned on SLAB debugging and here is the message I got:
slab: Internal list corruption detected in cache 'buffer_head'(30),
slabp ffff81007e100100(1515870810). Hexdump:
