<!-- Thank you for using postmarketOS! In order to speed up process of resolving your issue, we would like you to fill in the following form. *** NOTE FOR CONFIDENTIAL ISSUES: *** A lot of people can read confidential pmaports issues! If you want to submit something that only the postmarketOS Core Team can see, write to team@postmarketos.org instead of opening an issue here! --> ### Describe your issue The graphics stack regularly implodes and leaves user stranded with black screen on Allwinner PinePhone. Usually ssh still works. This happens multiple times a week, on the run this usually requires a hard reset. Some more extra info: - When this happens the backlight usually doesn't turn on either when pressing the power button. However, the notification LED blinks and the device is warm. - Often this happens after not touching the device for a while and it just sits there and does network routing and wifi hotspot for some hours. I then encounter it when I want to directly use it again when I leave the house, hence why I usually don't have the time to SSH into it at that point. #### What's the expected behaviour? graphics stack doesn't implode #### What's the current behaviour? it implodes #### How to reproduce your issue? use phone for a while. high cpu and high i/o load might help. ### What device are you using? <!-- Leave name of your device in vendor-codename format.
