dmesg under 4.3.5

Upon updating to linux-4.4.1 from linux-4.3.5, Xorg is unable to run in the native 1920x1080 resolution and instead defaults to 1027x768.  Downgrading back to the 4.3 series kernel fixes this problem.

System architecture: x86_64
Kernel version: 4.4.1
Linux distribution: Arch
Mother board model: GA-EG45M-UD2H with onboard Intel GMA X4500HD
Display connector: HDMI

Distro driver and Xorg details:
xf86-video-intel 1:2.99.917+519+g8229390
libva-intel-driver 1.6.2
mesa 11.1.1
xorg-server 1.18.0

Attached are 4 files, matched pairs of dmesg+Xorg.log under 3.4.5 and 4.4.1 with the debug kernel flag 'drm.debug=0x1e log_buf_len=1M' in the grub line.  Please let me know if you need additional info.

Comment 4 Nobody 2016-03-01 21:49:12 UTC 
can you share what processor are you using on that board - GA-EG45M-UD2H
Comment 6 Jani Nikula 2016-03-08 11:19:52 UTC 
[    4.376702] [drm:intel_hdmi_detect] Live status not up!

Please try 4.4.4 or v4.5-rc7.
Comment 7 John 2016-03-10 21:09:37 UTC 
I will do this over the weekend, thank you.
Comment 8 John 2016-03-27 15:19:37 UTC 
v4.4.6 exhibits the same behavior
Comment 9 Ville Syrjala 2016-05-10 16:33:05 UTC 
Please test 4.5 or if that doesn't help 4.6-rc7.

The commit of interest in 4.5 is:
8d409cb3e8a2 ("drm/i915: Fix hpd live status bits for g4x")

and the one in 4.6-rx7 is:
60b3143c7cac ("drm/i915: Fake HDMI live status")
Comment 10 John 2016-05-10 18:56:42 UTC 
This hardware has been retired; recommend closing this bug report unless other users are able to debug further.
Comment 11 Ville Syrjala 2016-05-11 14:03:29 UTC 
(In reply to John from comment #10)

All right. I presume this should have been fixed by one of these
8d409cb3e8a2 ("drm/i915: Fix hpd live status bits for g4x")
60b3143c7cac ("drm/i915: Fake HDMI live status")

so marking as fixed (since we lack a proper status for "can't test anymore")
