dmesg errors

I installed Ubuntu Mate 17.10 and M-bab drivers (https://github.com/M-Bab/linux-kernel-amdgpu-binaries, without them one monitor is always black but powered on).

Almost every day system freezes suddenly after random amount of time, which can be from 5 minutes to 3+ hours. Only power button helps, no logs are saved but dmesg has errors.

I think this is either AMDGPU bug or something ryzen related (most likely not, because they manifest as sudden reboots, never as system freezes. And last bios update stopped them 2 months ago).
