Hello, I'd like to recommend backporting this commit: commit 0a363e85cdafbceeee6a49b91c604d0d4d070dc7 Author: Hans de Goede <hdegoede at redhat.com> Date: Thu Jul 23 17:20:12 2015 +0200 drm/nouveau/nv46: Change mc subdev oclass from nv44 to nv4c This disables MSI by default on G72 (NV46) devices where it's apparently a bit buggy. We have a later patch which turns MSI back

So I cannot take it into 3.12. Doh! I could have sworn that this commit was also backported, but I guess not. I did a big more digging, a few results: (a) v3.12 didn't actually have MSI enabled by default. It got turned off in one of the rc's, and didn'...

Several users have, over time, reported issues with MSI on these IGPs. They're old, rarely available, and MSI doesn't provide such huge advantages on them. Just disable.
