Subject: Linux 4.14 - BUG: unable to handle kernel paging request at
 ffffffff3bbbe160 IP: audit_signal_cb+0x75/0xf0

Hi John,

I am seeing the following on my laptop. Unfortunately this is my primary
system and my ability to bisect might be a bit limited. The system is
running 

4.14.0+ #4 SMP Tue Nov 14 19:25:58 MST 2017 x86_64 x86_64 x86_64 GNU/Linux

on Ubuntu 17.10 base.

Is this a known issue? Please see the dmesg excerpts below:


thanks,
-- Shuah
