After upgrading from kernel 4.14.99 to 5.4.27 the framebuffer stall the GPU and only a black image was shown. This could be reprocuded on an Igel UD 7 (CARRIZO) and a Lenovo 14w (STONEY) lspci -vv is attached from both devices. We did some more investigation to find the breaking change please see attached git bisect log: 6c8d74caa2fa33908ecd07fb1cf1b7bc629b367a is the first bad commit After finding the bad commit we reverted the changes on the 5.4.27 and framebuffer started working again. Patch for reverting is also attached.
