Fatal trap 12

[Manuel Stühn]

Since upgrading my Lenovo T450 from r333740 to r334167 I'm experiencing
several "Fatal traps 12". Before the update i did not have any of those.
In all cases the traps occured some time after resume.

Below there is some output found in /var/crash/core.txt

Aren't you the guy using the drm-kmod if yes, your custom complied kernel
and not the default kernel causing those issues.

I'm indeed using graphics/drm-stable-kmod, but i do not use a custom
kernel:
uname -rsmv
FreeBSD 12.0-CURRENT FreeBSD 12.0-CURRENT #8 r334167: Thu May 24
20:06:20 CEST 2018
***@valinor:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG amd64

The drm-stable-kmod was installed from ports with the corresponding
src-tree.

Since upgrading my Lenovo T450 from r333740 to r334167 I'm experiencing
several "Fatal traps 12". Before the update i did not have any of those.
In all cases the traps occured some time after resume.

I tried to debug this further by building different kernel versions (all
GENERIC-NODEBUG). The last working revision is r334117, the first not
working is r334123. Revisions 334118-334122 of the kernel did not build,
so i cannot try these.

Any ideas what could cause these issue?
