dmesg output after booting with the DP connector already connected (not a "hot
plug")

After uploading my last two attachments (see above), another test occurred to
me, so for what it's worth...

This time I tried connecting the external monitor BEFORE booting the notebook
(so, no "hot plugging").  Test Result: No signal reaches the external monitor
(exactly as in the other tests).  The one possible difference is that the last
thing in the dmesg output - before I disconnected the adapter - was a number of
our good old "*ERROR* too many retries" error messages.  

So, apparently I have to retract even my weak attempt at "good news" (see
above).  

By the way, I disconnected the adapter before capturing the dmesg output (this
attachment), so you'll see that in the dmesg output after the "*ERROR*"
messages.
