Hello all, my RV610 gpu has issues when resuming. I usually get the screen i
posted. When that screen appears, the only solution ive found is to Ctrl+alt+f3
and reboot the system. That screen will sometimes flicker, or even briefly show
the login screen before going back to it. One day I noticed some messages maybe
describing the bug shown in attachment 2
