Hi,

I have upgraded to FreeBSD 12-CURRENT (2017/11/03) with GENERIC-NODEBUG config
for the kernel.

% uname -a
FreeBSD bs.local 12.0-CURRENT FreeBSD 12.0-CURRENT #0: Sat Nov  4 00:38:39 CET
2017     root at bs.local:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG  amd64

Next I have upgraded all packages to be up to date with 'pkg upg' and then
added 'drm-next-kmod' port.

Then I added 'kld_list="/boot/modules/i915kms.ko"' to /etc/rc.conf and
rebooted.

Upon boot there are messages that firmware from 'gpu-firmware-kmod' package
failed to load so there would be no power management.

After I started X11 then 'XFCE Destop' loaded and is usable, but any 3D
application (glxgears/kodi) or movie player (mpv/vlc) ends with Segmentation
Fault.

What other information do You need from me to dig the problem further and fix
that behavior so there would be working 3D, movies acceleration in hardware and
proper power management?

Also HDMI output does not work, VGA output works.


Regards,
vermaden
