            Bug ID: 91254
           Summary: (regresion) video using VA-API on Intel slow and
                    freeze system with mesa 10.6 or 10.6.1
           Product: Mesa
           Version: 10.6
          Hardware: x86-64 (AMD64)
               URL: https://bugs.archlinux.org/task/45459
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org

After upgrading to mesa 10.6.0-1 from 10.5.7 under the Intel Graphics, with the
work of the VA-API display slows down and freezes.

Additional info:

* package version(s)
mesa 10.6.0-1
mesa-libgl 10.6.0-1

* config and/or log files etc.
System: 4.0.6-1-ck x86_64 (64 bit), (tested also 4.0.5-2), Desktop: KDE (Plasma
CPU: Dual core Intel Core i5 M 450 (-HT-MCP-) cache: 3072 KB 
Graphics: Card: Intel Core Processor Integrated Graphics Controller
Display Server: X.Org 1.17.2 driver: intel Resolution: 1920x1080 at 60.00hz
GLX Renderer: Mesa DRI Intel Ironlake Mobile GLX Version: 2.1 Mesa 10.6.0

The problem is on Intel Core i5 M 450 - first generation (Nehalem) of Intel
Core, also tested on the i3-3220T - third generation (Ivy Bridge) and i3-4005U
fourth generation (Haswell) and it works properly.
I did not test for second-generation (Sandy Bridge).

Steps to reproduce:

Metod 1
- install mesa 10.6.0-1 and mesa-libgl 10.6.0-1 (or 10.6.1)
- install mpv and configure it:
- play any video,

Metod 2
- install mesa 10.6.0-1 and mesa-libgl 10.6.0-1
- install kodi
- enable VA-API (Settings > Video > Acceleration)
- play any video

Symptoms: display slows down and freezes

Tested on:
- xf86-video-intel 1:2.99.917+364+gb24e758-1 and 2.99.917-5
- AccelMethod, SNA, UXA, glamor
- Linux 4.0.6, 4.0.5-2, 4.1.1

On most video files you can see the problem, but not all.
You can test to: Jellyfish Video Bitrate Test Files http://jell.yfish.us/

It helps only downgrade to mesa and mesa-libgl to 10.5.7-1

Does not help downgrade xf86-video-intel to 2.99.917-5, therefore the suspicion
that the problem is mesa.

Upgrade libva and libva-intel-driver from 1.5.1 to 1.6.0 does not resolve this
