Comment 1 Boris Ranto 2017-12-07 17:15:05 UTC 
You are hitting a kernel NULL pointer dereference. That is a kernel bug, reassigning.
Comment 2 Laura Abbott 2017-12-07 19:01:56 UTC 
Can you attach the full kernel log and lspci -vvv
Comment 3 Laura Abbott 2017-12-07 19:06:05 UTC 
https://bugzilla.kernel.org/show_bug.cgi?id=197999 this looks to be a known regression with a fix.
