# make modules_install && make install
Reproducing issue:
1. Launch any browser (I checked on Firefox and Opera)
2. Open <a href="http://www.graphicsfuzz.com/benchmark/android-v1.html">http://www.graphicsfuzz.com/benchmark/android-v1.html</a>
3. Press Go
4. Wait when reached shader15 test
Symptoms:
1. The system stop to respod.
2. All the LEDs on the video card showing the load start to glow.
3. The turbine on the video card starts to make a lot of noise.
In dmesg appears follow lines:
[drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled
seq=71473, last emitted seq=71475
[drm] No hardware hang detected. Did some blocks stall?
If you are used Opera browser before would be added follow lines:
[drm:gfx_v9_0_priv_reg_irq [amdgpu]] *ERROR* Illegal register access in command
stream
[drm] No hardware hang detected. Did some blocks stall?</pre>
