The hang looks deep inside a mesa batch. First task is to find which application submitted that batch and how to reproduce the hang.

Hi,

I'm kinda new in this stuff. Can you guide me how to do it ?

I have something similar here, on a kernel 4.4.0 64 bits (from Ubuntu).

This happens easily when using LibreOffice (v5.1.2), with Unity 7 as window/composite manager.

This happens only since I've uninstalled 'xserver-xorg-video-intel', so Xorg is using the modesetting module.

Can someone capture and upload an apitrace (https://github.com/apitrace/apitrace) that reproduces the issue? Tell us how to reproduce? Try mesa-13.0.0?

Please test a new version of Mesa (13.0.0) and mark as REOPENED
if you can reproduce and RESOLVED/* if you cannot reproduce.

Dear Reporter,

This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested.

Thank you.
