Public bug reported:
The problem is observed while debugging lp:1955720. The AMD RX 640 fails
to work in kernel 5.14 and even the latest 5.17-rc. After kernel
bisecting, I found disabling ASPM (reverting commit 0064b0ce85bb
("drm/amd/pm: enable ASPM by default")) can display w/o problem.
However, the display seems to respond very slow to keyboard/mouse input.
Created a bug on https://gitlab.freedesktop.org/drm/amd/-/issues/1907 for
tracking.
