--- Comment #7 from Timur Kristóf venemo@msn.com --- 1. It was suggested that this is a thermal issue. So I monitored the GPU temperatures with GALLIUM_HUD and it was about 40 Celsius when the crash happened.
2. It was also suggested that this is a VRAM memory leak. Again with GALLIUM_HUD I could see that about 1 GB of VRAM gets used (out of the 4 GB), when the crash happens.
3. Also, just to see if this is a power consumption issue (ie. the GPU drawing more power than can be supplied), I tried to lower the value from /sys/class/drm/card0/device/hwmon/hwmon0/power1_cap to 80 Watts. It did not stop the crash from happening.
