Well there are two problems here

1) Kernel warning:  drm_irq.c:1326 drm_wait_one_vblank+0x191/0x1a0
[drm]().....This is probably due to
https://github.com/torvalds/linux/commit/74c090b1bdc57b1c9f1361908cca5a3d8a80fb08
as stated in https://bugs.freedesktop.org/show_bug.cgi?id=93782

This can be fixed in by appending "video=SVIDEO-1:d" to kernel boot
command.


2) It's this bug which still exists in v4.10-rc7. The possible cause is :

ea0000f0d369a59c2086fe9c489e0a2a86e080ba - drm/i915: Roll out the helper
nonblock tracking.

A patch (https://patchwork.freedesktop.org/patch/128918/) was proposed
to disable it But according to @Jim Rees's comment on the patch they are
not going to push it 4.9 and it may not land for 4.10 either.

So that means I have to manually apply the patch and see if it gets
fixed.

Title:
  drm/i915: Unity-control-center (or any other settings module) makes
  the system unresponsive (Unity7, Zesty) for Kernel > 4.6

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After upgrading driver from 2:2.99.917+git20160325-1ubuntu1 to
  2:2.99.917+git20160706-1ubuntu1,

  Whenever I open ¨Unity-Control-Center¨ makes the system unresponsive
  for a while and sometimes forever. Same thing happens if I try to open
  power or sound settings from indicators or when I try to add online
  accounts in evolution.

  I can reproduce same with totem. But all other applications are
  working fine. And everything works in Yakkety.

  Screencast:https://youtu.be/69PJZf055V8

  I am happy to provide any other debugging info. Just don ask to use
  ¨apport collect¨ as it hangs as well! I can provide details manually
  through syslog or something.

  System: Custom made (Intel Core2duo, 4GB RAM, Intel Mobile GME965/GLE960 
Integrated Graphics)
  Graphics driver: i915
  Os: Ubuntu 17.04, 32bit
  UCC: 15.04.0+17.04.20161125.1-0ubuntu1

  Edit: If I boot to recovery and use gallium 0.4 on llvmpipe, problem
  disappears as well. That is why I think itś some sort of graphics
  issue.
