Another interesting thing. I changed the boot file to only
"video=HDMI-A-1:e" and the monitor on the DVI port complains about the
resolution being to high. I then put the hdmi cable onto my dvi/hdmi
adapter and plug it into the DVI port and wala, a 1920 x 1080 desktop. So I
reboot with it in that configuration and again comes up good connected to
the DVI connector.
So at least the EDID firmware now gets recognized and considered :)

I'm still getting the same messages spewed into the kernel log file. So
this looks to me like the kernel is confused. Again, I ask, why do I have 3
HDMIs and 3 DPs but just one VGA.
Maybe Daniel or Chris can comment on that high quantity of DP/HDMI
connectors seen by driver. Those are probably also the cause of the
persistent EDID complaints in kernel log.
What I see is that HDMI-1 is the DVI port, HDMI-3 is the HDMI port, so I
assume HDMI-2 is that "other" video port.
If I set video=HDMI-A-1:d nothing comes out the DVI port and if I set
HDMI-A-3:d nothing comes out the HDMI port. This is rather confusing. Is it
correct?
You could maybe try to disable those outputs in xorg.conf in order to not
get your log filled with bad EDID complaints for "unused" connectors.
But as specifying the EDID as firmware it's just a work-around to the
issue.
These messages get spewed even if X is not running. The machine is
unresponsive for 2-3 seconds when this happens.
Sure, specifying the EDID as firmware is a work around, but it's a work
around that isn't working as intended on this hardware, for whatever
reason. Seems like someone would be interested in fixing it? I've got a
machine I could provide some access to?
