--- Comment #21 from Arcadiy Ivanov <arcadiy at ivanov.biz> ---
Got the GPU hang dump via the following script:

```
#!/bin/bash -eEu

while grep -q '^No error' /sys/class/drm/card0/error ; do 
    sleep 0.3 
done

cat  /sys/class/drm/card0/error > /card0_error.dump
sync

```

running it as 

`sudo nohup ./monitor_gpu_error.sh &`
