dmesg output from last crash

Hello. I been following issues here for more than a month now, looking for any
fixes or at least workarounds for my problem. I've had multiple errors, but
most of them are now:

[drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled
seq=648885, last emitted seq=648887
[drm] GPU recovery disabled.
[drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout, last signaled
seq=94380, last emitted seq=94383
[drm] GPU recovery disabled.

Arch Linux, mesa-git and others from this repository
(https://pkgbuild.com/~lcarlier/mesa-git/), kernel 4.18.0-rc5, Sapphire Radeon
RX 580 8G NITRO+. I've tested this issue on multiple configurations, both
stable mesa and kernel crashed at least 2 times daily, all crashed for me, but
at least now I get at least full day between them. For some reason all crashes
occurred on either: watching videos on youtube, -normal light webpage browsing,
-watching videos with mpv (acceleration disabled).

I've used amdgpu before on HD 7850 for a few months without any crashes ever
(probably without DC) on the same setup.

If it's some program fault, please at least point me to a method how to find
out which.
