Here's a log of the drm parts: https://pastebin.com/tFJ9Gs6h linux-next also hangs. > Can you share the EDID of your monitor ? Maybe not mode related. I tried forcing to 1280x720 and it hangs too. In any case, here's the parsed EDID: 256-byte EDID successfully retrieved from i2c bus 3 Looks like i2c was successful. Have a good day.
