Hi Ben,
3.7-rc1 messed up the screen on my MacBookAir3,1 (nv50, 0xaf) pretty badly. Not surprisingly,
commit 3863c9bc887e9638a9d905d55f6038641ece78d6 Author: Ben Skeggs bskeggs@redhat.com Date: Sat Jul 14 19:09:17 2012 +1000
drm/nouveau/instmem: completely new implementation, as a subdev module
is the first bad commit. Standing on that commit, booting and then starting X yields the output below. Hints are especially appreciated, considering the patch is almost 8000 lines.
Thanks, Henrik
