--- 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 &`
