The settings are 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 frequencies. The key must be something in the Linux firmware for this card.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
