dmesg
When disconnecting a second monitor on a AMD Ryzen 5 2500U with Radeon Vega
Mobile Gfx the system seems to hang. It is reachable over a wired connection,
but the screen (other than a moving mouse) does not repond to any input.
Connecting new devices such as an external mouse does not seem to influence the
running session.
Connected over netconsole, and later direct via the wired connection the error
presented in dmesg:
[drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR*
[CRTC:70:crtc-1] flip_done timed out
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[CRTC:70:crtc-1] flip_done timed out
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[PLANE:50:plane-2] flip_done timed out
