I am seeing following kernel backtrace on J6 with linux 3.8.13 when trying

Dear All,
What is the most effective/optimal/recommended way to wait for
DRM_MODE_CONNECTED status?
This is to make sure when disply manager (uses drm apis) starts and if it
do not get the DRM_MODE_CONNECTED status as some dependent driver is still
loading and setting up (e.g. serializer driver)
