Subject: do_raw_spin_lock, BUG: kernel NULL pointer dereference, address: 0000000000000084


I keep up-to-date with Greg's stable releases.

I've seen three of these BUGs this year, none earlier than 5.6.7.

They occur randomly and infrequently, so impossible to bisect.

Afterwards, processes end up hung in "D" state, and can't be killed.

The tainting is due to loading this module:
May 08 17:43:55 bilbo kernel: xt_TARPIT: loading out-of-tree module taints kernel.
from http://xtables-addons.sourceforge.net/
This module has been loaded for a very long time, I'd hope that this isn't the cause.
