Blank screen after enabling amdgpu.seamless on a Barcelo APU

Mon Feb 12 10:03:25 UTC 2024

Hello team,

Testing "amdgpu.seamless=1" on Ryzen 7 5825u using kernel 6.7.4 led to a 
blank screen after the initial boot screen as tested on Dell Inc. 
Inspiron 14 7425 2-in-1 with the following message from boot:

"Feb 11 13:43:37 kernel: amdgpu 0000:04:00.0: [drm] *ERROR* 
[CRTC:73:crtc-0] flip_done timed out"

Here is the journalctl report sorted by amdgpu:

Should I submit the issue to the kernel bug report or here?
