Description

On a regular (almost daily) basis, my two screens turns black and no movement of the mouse or keyboard brings it back to life. The system itself seems to be still running properly, I can access the system remotely and I can shut it down cleanly.

System is a HPZ620 workstation, OS is a current Arch Linux (rolling release with up-to-date drivers, kernel 4.18.6), card is a RX Vega 64, the two screens are connected via displayport.

The following error is the only one that occurs each time when the screens give up:
