Comme= nt # 15 on bug 10542= 5 from MirceaKitsune 
Today I've ran two tests to ensure that frequencies and DPM ar=
e not a factor.

- Setting the DPM profile to low by running the following commands as root:

    echo battery > /sys/class/drm/card0/device/power_dpm_state
    echo low > /sys/class/drm/card0/device/power_dpm_force_performance_l=
evel

- Booting my system with the following Kernel parameters to disable DPM:

    radeon.dpm=3D0 amdgpu.dpm=3D0

Just like with everything else, they made absolutely no difference: Xonotic
froze the machine after only 8 minutes of running each time. The settings a=
re
applied and visible by checking /sys/kernel/debug/dri/0/amdgpu_pm_info, and=
 are
even reflected in the performance which was reduced from 60 FPS to below 30
FPS.

This is NOT a hardware failure: The freezes occur identically even if both =
the
core (GPU) and memory (VRAM) clocks are under-clocked to very safe frequenc=
ies.
The key must be something in the Linux firmware for this card.
