Hi everybody! I have exactly the same problem as Oleksandr (upgrading from
kernel 4.1.16 to 4.4.6, but also 4.4.8 and 4.5.3 are affected)
This is my environment info:
# uname -a
Linux 4.4.6-gentoo #2 SMP Fri Apr 29 01:42:29 CEST 2016 x86_64 Intel(R)
Core(TM) i5-3470 CPU @ 3.20GHz GenuineIntel

Unfortunately I'm out of ideas for now. Daniel is on vacation.
Ville, Daniel,
any additional info I could provide? I have to return dual-link DVI

Ville,
here is another dmesg: [1]
I've reconnected HDMI cable three times.
Forgot to note, it is HDMI monitor plugged into machine's DVI with
HDMI-DVI cable. I guess this should matter as well.

Daniel,
I do confirm that this hacky patch:

works around my issue. I understand that this is improper fix, so let me
know how could I debug my issue further.
Thanks.
