Bug#1022042: linux-image-amd64: linux-image-5.10.0-19-amd64 fails to boot on machines with AMD integrated graphics

[Arndt Kaiser <aka@mrwash.de>]

Dear Maintainer,

i can confirm the problem.

All of our notebooks with integrated AMD graphics (CPU: AMD Ryzen 7 PRO 
4750U with Radeon Graphics) are affected and don't boot anymore.

During boot the following error-messages appear:

[drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* 
[CRTC:62:crtc-0] flip_done timed out.

[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* 
[CRTC:62:crtc-0] flip_done timed out.

[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* 
[PLANE:52:plane-3] flip_done timed out.


5.10.0-18 boots without problems.


Best Regards,

Arndt Kaiser
