I did a bisect on mesa 17.2 and tracked down the change that broke vaapi. The change is specific to Gen8+ GPUs. It affects Broadwell GPUs for sure and possibly Skylake+ GPUs.

@maximbaz If you have time to make your own mesa-17.2 build, can you try reversing the patch (only the third block needs to be backed out: brw_state_upload.c)? No one else commenting that they have the issue.

It fixes the vaapi problem on my laptop and doesn't seem to break anything else.

Additional info:
* package version(s)

* config and/or log files etc.

Steps to reproduce:
1. install mesa-17.2
2. install chromium-vaapi-bin
3. enable vaapi accelaration
4. open a HTML5 video
5. expected playback smoothly, but actually freeze the whole process
This task depends upon

You can try the Mesa 17.2.1 (released last night).

If the issue is still there - do open a bug against Mesa see [1].
Informing the developers about this regression.

I got the same problem with mesa since the update to 17.2. My system freeze, when playing mp4/h264 videos.
The problem can be fixed by downgrading the mesa package to mesa-17.2.1-3-x86_64 and leaving all other packages as they are.
Processor is Intel Core i5, Clarkdale i5-660 @ 3.3GHz x 2 (Westmere architektur) and integrated GPU with HD Graphics (Ironlake).

I doubt Arch maintainers will be able to sort out the issue. Please report it upstream?

The fix is here:

Please patch. Thanks!
