Preparing:
1. install Fedora 27. https://download.fedoraproject.org/pub/fedora/linux/releases/27/Workstation/... 2. install latest MESA and LLVM https://copr.fedorainfracloud.org/coprs/che/mesa/ 3. build and install staging kernel with latest amdgpu driver $ git clone git://people.freedesktop.org/~agd5f/linux --branch amd-staging-drm-next $ cd linux $ make clean && make bzImage && make module # make modules_install && make install
Reproducing issue: 1. Launch any browser (I checked on Firefox and Opera) 2. Open http://www.graphicsfuzz.com/benchmark/android-v1.html 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?
