Subject: 4.12 nf_conntrack_expect crash

Hi,

on my system, I see a crash in del_timer invoked in nf_conntrack_expect.
See the attached picture.

I somehow suspect this commit:

commit ec0e3f01114ad327112432a4da8840eb22fed577
Author: Gao Feng <fgao@...ai8.com>
Date:   Mon Mar 27 10:31:26 2017 +0800

    netfilter: nf_ct_expect: Add nf_ct_remove_expect()


I am going to play with it (debug, try to revert, etc.) if you have no
better idea...

thanks,
