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: (http://advdownload.advantech.com/productfile/PIS/dpx-s440/Product%20-%20Datasheet/DPX-S440_DS(04.27.17)20170505095524.pdf)
