crash information from dmesg

drm-fbsd12.0-kmod on FreeBSD 12-STABLE/amd64, i915kms.ko, Xeon E3-1225v3 (Haswell).

Executing glxgears on a remote system with SSH X11 forwarding immediately crashes the local system.
$ ssh -Y remote_host glxgears

(The same also happened with drm-stable-kmod-g20180822_1, 11-STABLE/amd64, radeonkms.ko and xf86-video-ati-18.1.0,1 on a Radeon 5450.  However, I have by now replaced that configuration with the Intel one above.)

See the attached crash information extracted with dmesg.
Comment 1 Johannes M Dieterich freebsd_committer freebsd_triage 2018-12-26 21:31:50 UTC 
This is not a problem with the port itself but with the actual DRM. Please report this upstream (i.e., https://github.com/FreeBSDDesktop/kms-drm ) which is where these issues are being tracked and where they are being worked on and fixed. Thanks.
