Unfortunately, the problem is still there even with kernel 4.3 vanilla.

After the system boots, the external monitor works, I can drag windows to it,
etc. But when I try to make it the main output, the screen flickers a bit and
the external monitor can no longer be used.

I will attach the new logs below.

"too many retries, giving up" message is output several times there.

Additionally, when I try to switch to the external monitor, there is the
following warning, not sure if it is related:
