Xorg.0.log after a crash.

I'm starting X with "xinit -- -depth 16" with a single display connected
through a Display Port connector. When I then try to configure screen
resolution, the server crashes with the backtrace as in log file. Operating
system is Arch Linux running under 4.9.78-1-lts kernel.

Motherboard model is Advantech DPX-S440:
