Alright, any hint where to start looking? As I said before it looks like the visual corruption (this <a href="https://pasteboard.co/qrC9mh4p.jpg">https://pasteboard.co/qrC9mh4p.jpg</a>) at boot starts at [drm] amdgpu atom DIG backlight initialized [drm] AMDGPU Display Connectors [drm] Connector 0: [drm] eDP-1 [drm] HPD1 [drm] DDC: 0x4868 0x4868 0x4869 0x4869 0x486a 0x486a 0x486b 0x486b [drm] Encoders: [drm] LCD1: INTERNAL_UNIPHY [drm] Connector 1: [drm] HDMI-A-1 [drm] HPD2 [drm] DDC: 0x486c 0x486c 0x486d 0x486d 0x486e 0x486e 0x486f 0x486f [drm] Encoders: [drm] DFP1: INTERNAL_UNIPHY [drm] amdgpu atom DIG backlight initialized [drm] AMDGPU Display Connectors [drm] Connector 0: [drm] eDP-1 [drm] HPD1 [drm] DDC: 0x4868 0x4868 0x4869 0x4869 0x486a 0x486a 0x486b 0x486b [drm] Encoders: [drm] LCD1: INTERNAL_UNIPHY [drm] Connector 1: [drm] HDMI-A-1 [drm] HPD2 [drm] DDC: 0x486c 0x486c 0x486d 0x486d 0x486e 0x486e 0x486f 0x486f [drm] Encoders: [drm] DFP1: INTERNAL_UNIPHY Fortunately it disappears after ~2 seconds when plymouth kicks in. My impression is that the visual corruption is triggered again when interpreting some atombios code, not really easy to debug.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
