I can confirm system freezes while playing Grid Autosport, although they also happen while driving or navigating in the menus.
I'm on RadeonSI with an A10-7850k and integrated graphics though, would this be a new bug then? Mesa version is 11.1.1.

I think it's separate bug, but you never know.
I would open separate bugreport and worry about duplicates later.

I am pretty sure this is the bug with xpad that can cause hangs when using force feedback. This was reported by Feral during development of XCOM and was fixed for SteamOS by Pierre-Loup but the fix has not made it's way upstream to the main linux kernel.

This was fixed by Sarah Bessmer (see link here)

http://www.spinics.net/lists/linux-input/msg31450.html

Pierre-Loup also fixed the issue separately himself for the SteamOS drivers.

Sarah's fix has been used by a number of people with a lot of success and we have also confirmed the SteamOS drivers don't see this issue so hopefully one of the two fixes can be merged into xpad to fix this problem.

Hope this background helps!

Mine or Florians bug you are talking about?

I suspect both have the same cause. 

1. Can we please to a reproduction test using 11.2? That had a lot of Autosport related fixes.

2. We have a beta patch available via support that will disable the force feedback part of the pad code you can request access to the beta by emailing linuxsupport@feralinteractive.com and explaining your situation.

Marking as NEEDINFO as I suspect this issue is not related to Mesa see previous comment for details.

i'm affected of the same bug, i also filled a bug report here:

https://bugs.freedesktop.org/show_bug.cgi?id=93353

After a request to the Feral support, i tested the patch but the GPU still stall when the game is loading at the end of the qualifications.

I was affected by this bug for a long time but it seems to be fixed now in the latest mesa git.

I am running ubuntu 16.10 on a i7 920 with a AMD Radeon RX480 with mesa stack upgraded with padoka PPA
